The bathroom is the smallest room in the house and, paradoxically, one of the easiest to get wrong. In just a few square metres you bring together water, drainage, electricity and constant humidity, and almost all the decisive work —the waterproofing, the falls, the plumbing— ends up hidden beneath the tiles. When any of that is rushed, you won’t see it on handover day: you’ll see it six months later, as mould, a lifted joint or a damp patch on the neighbour’s ceiling. At Batecs we have spent more than 35 years renovating bathrooms in Valencia, La Eliana and the Camp de Túria, and we look after what you can’t see just as carefully as what you can.
We work the opposite way to most of the trade. Instead of you coordinating the plumber, the tiler and the screen fitter yourself, a single site manager plans the phases, lines up the trades and keeps you informed. You choose the sanitaryware and the finishes; we make sure the bathroom is handed over when we said it would be, for the price we agreed, and with the fewest possible days without a bathroom.
Whether you want to swap the bath for a walk-in shower, make the most of a small bathroom, adapt it for an older relative or renovate it completely with materials that last for years, this is the service that brings it all together. And if the work goes beyond the bathroom, take a look at our full home renovations too.
01 A complete service
What a bathroom renovation includes
A genuinely new bathroom, from the waste pipe to the last joint —not a quick facelift that lasts two years.

Strip-out and building work
We remove the old sanitaryware, tiling and tray, deal with the rubble and prepare the walls and floor so we start on a sound base.

Plumbing and sanitaryware
We renew pipework, waste and sanitaryware —toilet, basin, bidet— and leave the installation ready for many years, not patched up.

Shower and screen
We swap the bath for a flush-fitted, anti-slip shower tray, with a made-to-measure screen and thermostatic taps.

Tiling and floors
Porcelain, large-format or microcement, always laid over properly executed waterproofing beneath the tray and the wall finishes.

Furniture and lighting
Wall-hung units, basins, mirrors with built-in light, a towel rail and warm, functional lighting, chosen for both design and durability.

Ventilation and damp
Properly sized extraction and ventilation to prevent mould and condensation after the work —not bolted on as an afterthought.

By scope
Types of bathroom renovation: from a shower swap to a complete refurbishment
Not every bathroom renovation starts from the same point or costs the same. Knowing which one fits your case helps you get your bearings before asking for a quote, and avoid paying for more work than you actually need.
Swapping a bath for a walk-in shower
The most requested bathroom renovation and, at the same time, the most contained. We remove the bath, prepare the base, waterproof it and fit a flush-fitted shower tray with its screen. It’s done in a few days without touching the rest of the bathroom, which makes it excellent value in terms of safety and space gained. It’s the standout choice for anyone who wants to get rid of the step over the bath without taking on major work.
Complete bathroom refurbishment
Renews the bathroom from top to bottom: plumbing, sanitaryware, shower tray, tiling, flooring, furniture and lighting. This is the typical renovation for an old bathroom that’s already causing problems or feels dated. Here it really is worth checking the pipes and waste while everything is open, because redoing it later means breaking it all up again.
Renovation with a new layout
The most far-reaching: as well as renewing everything, the shower, toilet or basin are moved, a bathroom is created where there used to be a box room, or a bathroom with a bath becomes one with twin basins. It involves more plumbing and sometimes altering partition walls, so it’s the one that needs the most planning. When it affects several rooms, it’s usually folded into a full home renovation.
02 Your bathroom
Find your situation
Every bathroom starts from a different challenge. These are the most common ones in Valencia and the surrounding area; click the one that looks most like yours.

Swap a bath for a shower
You want to lose the bath and gain a comfortable walk-in shower. The challenge: getting the waterproofing and the fall right.

Small bathroom
Just a few square metres in a flat. The challenge: creating a sense of space and using every corner without it feeling cramped.

Accessible bathroom
Adapting it for an older person or someone with reduced mobility. The challenge: a barrier-free shower, grab rails and anti-slip flooring.

Complete refurbishment
Renewing the whole bathroom, old or dated. The challenge: checking the services and choosing materials that last.
03 The standout renovation
Swapping the bath for a shower: the renovation that pays off most
By a clear margin, this is the bathroom renovation we’re asked for most —and for good reason. Replacing the bath with a flush-fitted shower tray makes the bathroom safer (the step that causes so many slips disappears), more spacious to the eye and far more comfortable day to day. In most bathrooms it’s done in just a few days of work, with no need to renew the rest.
The key isn’t the tray you can see, but what lies beneath it. We do the waterproofing before fitting anything and create the correct fall towards the waste, which is what prevents leaks to the flat below. On that base we then choose the tray —resin, porcelain or mineral-filled, anti-slip— and the made-to-measure screen.
Further down you’ll find an honest comparison of bath versus shower so you can decide with confidence, and if the change is for reasons of safety or accessibility, we link it to the adapted bathroom section.
04 Investment
How much a bathroom renovation costs in Valencia
No two bathrooms are the same, but market ranges do help you get your bearings before asking for a quote. These are indicative: we set the real price after the site visit.
| Type of renovation | Indicative price | What it usually includes |
|---|---|---|
| Bath swapped for a shower | ≈ €1,500-3,500 | Bath removal, waterproofing, flush-fitted shower tray, made-to-measure screen and taps, without touching the rest of the bathroom. |
| Complete bathroom · entry range | ≈ €4,000-6,500 | Full renovation with standard sanitaryware, simple tiling, a unit and a standard tray, keeping the existing layout. |
| Complete bathroom · mid range | ≈ €6,500-10,000 | Wall-hung sanitaryware, thermostatic taps, good large-format porcelain, a made-to-measure unit and renewed services. |
| Complete bathroom · high range | ≈ €10,000-16,000+ | New layout, microcement or large-format tiling, twin basins, a built-in shower, heating and designer lighting. |
Indicative market ranges for Valencia in 2026, for a medium-sized bathroom (around 4-6 m²), given for reference only. They are not a quote or an offer. The real cost depends on your bathroom, the square metres and the finishes you choose.
What affects the price
The price depends above all on the square metres, on whether the layout changes (moving the shower, toilet or basin pushes up the plumbing), on the level of sanitaryware, taps and wall finishes and on the condition of the existing plumbing. Swapping a bath for a shower doesn’t start from the same point as a complete renovation with a new layout.
That’s why we prefer to give you a fixed quote after the site visit, with the items itemised, rather than a «catalogue» price that doesn’t then match your bathroom. That way you know from day one exactly what you’ll pay.
Making your budget go further
How to keep the cost down without cutting what matters
Saving on a bathroom isn’t about choosing the cheapest of everything: it’s about knowing where to invest and where to hold back. After 35 years, this is what we usually advise anyone on a tight budget who doesn’t want to regret it later.
Don’t cut corners on what you can’t see. The waterproofing, the plumbing and the waste pipes are the bathroom’s «invisible structure». Saving there is the most expensive mistake in the medium term: a leak means breaking up tiling and a tray you’ve already paid for, and sometimes answering to the neighbour downstairs.
You can trim on sanitaryware and furniture. These days there are trays, units and taps with excellent value for money that give a great result. And you can always set aside a treat —a hydromassage column, a special wall finish— for later on.
Keeping the layout saves a lot. If you keep the shower, the toilet and the basin where they are, you save a good part of the plumbing work. Moving the fittings to the other side of the bathroom pushes the cost up; sometimes it’s worth it, but it’s good to know before you decide.

05 The Batecs method
How we handle your bathroom renovation
A clear, well-ordered process, designed to minimise the days without a bathroom.
Visit and measure-up
We assess the condition of the bathroom, take measurements and listen to what you want to achieve, with no obligation.
Proposal and finishes
We define the layout, sanitaryware and wall finishes, with a fixed quote itemised line by line.
Planning
We order the tray, screen, sanitaryware and tiles in advance to keep the days without a bathroom to a minimum.
Coordinated work
Strip-out, plumbing, waterproofing, tiling and fitting with our own team and a single site manager.
Quality control
We check the seals, the falls, the joints and that every water and light point works as it should.
Handover
We hand the bathroom over clean, sealed and ready to use, with nothing left outstanding.
The aim of all this coordination is one thing: that the bathroom is out of action for the fewest possible days. That’s why we don’t start the strip-out until the materials are on site, especially if it’s the only bathroom in the home.
06 The decision
Bath or shower: which suits you
There’s no single answer, but in most bathrooms in daily use the shower wins. Here’s what each option offers and what it gives up.
Safer and more spacious
- No step: much safer, especially as you get older.
- Adds a sense of space in small bathrooms.
- Easier to clean and to use every day.
- The basis for a barrier-free, accessible bathroom.
- Gives up the option of a long soak in the bath.
For soaking and young children
- Lets you enjoy a relaxing soak.
- Handy for bathing small children.
- Takes up more room and reduces the sense of space.
- The step is a slip risk as you get older.
- If you have a second bathroom, keeping a bath there can make sense.
Our practical recommendation: if it’s the main bathroom in daily use, a shower is almost always the better choice. If you have two bathrooms and you enjoy a soak, keep a bath in the second one and put a shower in the one you use every day. We’ll weigh it up against your specific case during the site visit.
Two very common cases
Accessible bathroom and small bathroom: how we solve them
Two of the enquiries we receive most often aren’t about looks but about need: adapting the bathroom for an older relative, and making the most of a bathroom with just a few square metres. Each has its own keys.
An accessible bathroom adapted for older people
An accessible bathroom doesn’t have to be a «hospital» bathroom: today it can be safe and good-looking at the same time. The keys are a barrier-free shower level with the floor, an anti-slip floor, well-anchored grab rails, a fold-down shower seat and, if needed, a toilet at the right height and more room to turn. Thinking about this during a normal renovation costs little more and avoids a second job years later. If the idea is to adapt the whole home and not just the bathroom, we tackle it within a full home renovation.
Small bathroom: gaining space without losing comfort
Flats in Valencia are full of bathrooms of 3 or 4 m², where every centimetre counts. Here we create a sense of space with tricks that genuinely work: a flush-fitted shower tray that unifies the floor, wall-hung sanitaryware that leaves the floor visible, a clear glass screen instead of a curtain, large-format tiles with few joints and furniture set up high. It’s not about cramming in more things, but about clearing the floor and the view so the bathroom can breathe.
07 Real projects
Bathroom renovation projects
A sample of the kind of bathrooms we renovate completely in Valencia and the Camp de Túria.

Modern bathroom with a shower
Complete renovation of an old bathroom in a flat in the Eixample: we swapped the bath for a flush-fitted shower tray, laid dark large-format tiles, fitted a wall-hung basin and a made-to-measure screen. We checked the plumbing and sorted the waterproofing to leave it ready for many years.

Designer bathroom with a shower
A bathroom with character: a coloured glass wall as the standout feature, a generous shower with a screen and thermostatic taps. We looked after every joint and the ventilation so that such a striking finish wouldn’t cause damp problems over time.

Spacious bathroom with shower and bath
In a main bathroom with room to spare, we kept the bath for the children and added a separate shower, all in beige large-format porcelain. A comfortable solution for a family who didn’t want to give up either the soak or the daily shower.
You can see more finished work in our gallery of projects, alongside kitchen, villa and whole-home renovations.
08 Finishes
Materials and sanitaryware: what really makes the difference
We advise you so that every material brings something —not just looks, but also durability, ease of cleaning and safety.

Shower trays
In resin, porcelain or mineral-filled materials, flush with the floor and anti-slip. Cut to size to fit any bathroom.

Screens
Made-to-measure tempered glass, fixed or folding, with an anti-limescale treatment. Clear, so a small bathroom feels more spacious.

Wall-hung sanitaryware
Wall-hung toilets and basins with a concealed cistern: they leave the floor visible, make the bathroom feel bigger and are easier to clean.

Thermostatic taps
Keep the water at the temperature you set and avoid sudden hot or cold surprises. More comfortable, safer and more efficient.

Wall finishes
Large-format porcelain and seamless microcement: fewer joints, less mould and a contemporary finish that’s easy to maintain.

Accessibility
Grab rails, fold-down shower seats, anti-slip floors and barrier-free showers for a bathroom that’s safe and comfortable at any age.
What you can’t see
Waterproofing and ventilation: the difference between a good bathroom and one that fails
Most problems in a renovated bathroom don’t come from a poor toilet, but from two things you can’t see: waterproofing done badly beneath the tray and the tiles, and insufficient ventilation. That’s why we treat them as an essential part of the job, not as an extra to cut back on.
Before fitting the tray and the tiles we apply a waterproofing membrane or resin and create the correct fall towards the waste; that way the water that seeps through the joints never reaches the structure or the neighbour below. And for ambient humidity we size the extraction properly: a bathroom with no window needs the right extractor fan so that mould and black marks don’t appear in the joints within a few months.
If your bathroom already has damp from an external source —a leak, water coming in from the flat above— we first track down the cause and repair it; simply covering the patch only delays the problem. You’ll see the same care in our finishes in painting and interior design.
09 Before you start
Mistakes worth avoiding when renovating the bathroom
- Skimping on the waterproofing or the fall of the shower tray, which is where leaks begin.
- Neglecting ventilation, especially in internal bathrooms with no window.
- Starting the strip-out before the tray, screen, sanitaryware and tiles are ordered and measured up.
- Keeping old, worn-out plumbing just to avoid breaking up while everything is open.
- Moving the shower or toilet without weighing up the extra plumbing cost.
- Choosing a floor that isn’t anti-slip, or sanitaryware that’s hard to clean.

Frequently asked questions
Frequently asked questions about bathroom renovations
How much does it cost to renovate a bathroom in Valencia?
As an indicative market guide, swapping a bath for a shower usually falls between roughly €1,500-3,500, while a complete bathroom runs from about €4,000-6,500 in the entry range up to €10,000-16,000 or more in the high range with a new layout. It depends on the square metres, the sanitaryware and wall finishes, and the extent of the plumbing. After the site visit we give you a fixed, itemised quote, with no vague entries.
How long does a bathroom renovation take, and how many days will I be without it?
Swapping a bath for a shower can be done in a few days. A complete bathroom usually takes one to two weeks depending on the scope. We order the tray, screen and sanitaryware in advance and don’t start the strip-out until we have everything, to keep the days without a bathroom to a minimum —especially if it’s the only one in the home.
Can you swap my bath for a shower?
Yes, it’s one of our most common renovations and one of the best value. We remove the bath, waterproof, create the correct fall and fit a flush-fitted, anti-slip shower tray with a made-to-measure screen. You gain safety, accessibility and a greater sense of space, usually in just a few days.
Can a bathroom be renovated without building work or breaking up?
There are low-impact solutions, such as overlaying a shower tray or using panels over the existing tiles, which work for very specific cases. But a bathroom isn’t genuinely renewed without touching the waterproofing or checking the plumbing: the cheap, no-building-work route tends to be short-lived. At the visit we’ll tell you honestly what scope your bathroom needs.
Do you do adapted bathrooms for older people?
Yes. We design accessible bathrooms with a barrier-free shower level with the floor, an anti-slip floor, well-anchored grab rails, a fold-down shower seat and, if needed, a toilet at the right height and more room to turn. It can be safe and good-looking at the same time, without looking clinical.
How do you gain space in a small bathroom?
With a flush-fitted shower tray that unifies the floor, wall-hung sanitaryware that leaves the floor visible, a clear screen instead of a curtain, large-format tiles with few joints and furniture set up high. The key is to clear the floor and the view so the bathroom can breathe, not to add more elements.
How do you prevent damp after the renovation?
With proper waterproofing beneath the tray and the tiles, the fall correctly resolved towards the waste, and well-sized ventilation. It’s the essential part of the job, not an extra. If there’s already damp from an external source, we track down the cause and repair it before we close anything up.
What do I do if my bathroom has no window?
An internal bathroom with no window needs a well-sized extractor fan connected to a duct that takes the humid air outside. With good extraction and low-joint materials (large format, microcement) you avoid mould and black marks. We sort it as part of the renovation.
Do I need a permit to renovate the bathroom?
A bathroom renovation that doesn’t touch the layout or the façade can usually be handled with a responsible declaration or works notification, depending on the municipality. If you change the layout or touch communal elements, it may require more paperwork. We advise you and handle the documentation needed so the work is fully above board.
Which materials last longest in a bathroom?
To avoid renovating twice: large-format porcelain or well-sealed microcement on the walls, a mineral-filled or porcelain shower tray, good-quality wall-hung sanitaryware and thermostatic taps. Whatever takes the most water is what’s least worth cutting costs on. We guide you according to your use and your budget.
What guarantee does the bathroom renovation carry?
We stand behind the work carried out and the materials in line with current regulations. What’s more, because we use our own team, we handle any later adjustment ourselves, without passing you on to third parties.
Do you only renovate the bathroom, or the rest of the home too?
We do both. We can renovate just the bathroom or fold it into a full renovation of the whole home. Many clients take the opportunity to renovate the bathroom and kitchen at the same time and save on travel and coordinating the trades.
Which areas do you carry out bathroom renovations in?
In the city of Valencia, La Eliana and every town in the Camp de Túria and l’Horta Nord: Paterna, Bétera, Godella, Llíria, Rocafort, Riba-roja, San Antonio de Benagéber, La Cañada and the surrounding area.
In short
A bathroom renovation in Valencia renews the room completely —plumbing, sanitaryware, shower tray, screen, tiling, furniture and lighting— looking after the waterproofing and the ventilation just as much as what you can see. At Batecs we carry it out with our own team, swap the bath for a shower or adapt the bathroom if you need it, and hand it over ready to use with the fewest possible days without a bathroom.
As an indicative market guide, swapping a bath for a shower comes in around ≈€1,500-3,500 and a complete bathroom runs from ≈€4,000-6,500 (entry range) to €10,000-16,000 or more (high range). We set the real price for your bathroom after the site visit, with no surprises.
