Bathroom and WC Renovation

Erdağ Yapı Dekorasyon renovates bathrooms and WCs in Istanbul on a turnkey basis: we propose several designs to suit you, then one team carefully handles plumbing, electrics, floor waterproofing, levelling and the final finish — tiles, Italian decorative plaster or, where suitable, wallpaper.

One Team for Bathroom and WC Renovation, from Design to Handover

The bathroom is the most used room in a home and the one with the most technical work: water, electrics, waterproofing and finishes meet in a few square metres. Erdağ Yapı Dekorasyon carries out bathroom and WC renovation from start to finish with a single team, paying attention to every detail. We start by listening to you and propose several designs to suit your habits and taste; then we build the design you choose, from the plumbing to the final finish.

Design Options Made for You

There is no single right answer for every bathroom. After measuring and inspecting the room during the site survey, we review different finishes and layouts with you:

Ceramic and porcelain tiles: The most durable choice for surfaces with the most water contact, such as the shower and the floor. From large marble-look formats to patterned tiles, we choose ceramic and porcelain tiles together.
Italian decorative plaster: For seamless walls with a silky or marble-like effect. We apply Italian decorative plaster on basin and WC walls with a water-repellent top coat; inside the shower, where water hits the wall directly, we recommend tiles or systems made for wet areas.
Wallpaper and textile wallpaper: Adds character in well-ventilated rooms with little steam where water does not reach the wall, such as a guest WC. Here we hang washable vinyl or textile wallpaper.
Micro cement: An alternative for a seamless, modern surface on floors and walls: micro cement.

You can see decorative plaster and wallpaper samples up close at our Erdeco Decoration Store in Esenyurt.

The Hidden Work: Plumbing, Electrics, Waterproofing and Levelling

A bathroom that works for years depends on the work hidden under the finish. That is why we carry out every stage in order and check it as we go:

Strip-out and preparation: Old finishes, sanitaryware and, where needed, old pipework are removed; rubble is cleared regularly and shared areas are protected.
Plumbing: Supply and waste lines are laid for the new layout; concealed mixers, in-wall cisterns and wall-hung toilet connections are prepared.
Electrics: Lighting, sockets, towel rail and extractor lines are run by our specialist team with wet-area safety in mind.
Floor waterproofing: Waterproofing is applied continuously on the floor and in the shower area, including corners and pipe penetrations, to prevent leaks to the flat below.
Levelling: The floor is screeded to fall towards the drain; walls are made flat, sound and ready for the finish.
Final finish and fitting: Your chosen tiles, decorative plaster or wallpaper are applied; basin, toilet, shower enclosure, mirror and accessories are fitted, and grouting and sealing are completed.

Because one responsible team handles every stage, nothing falls between different tradespeople. We provide a workmanship guarantee on the work we do.

Frequently Asked Questions

What does bathroom renovation include?

Strip-out, supply and waste plumbing, wet-area-safe electrics, floor waterproofing, levelling, the final finish (tiles, Italian decorative plaster or, where suitable, wallpaper) and fitting of sanitaryware, shower enclosure, mirror and accessories. One team handles every stage.

How do you start a bathroom renovation?

With a free site survey: we inspect your bathroom, take measurements and listen to what you want. Then we prepare several design proposals and an itemised written quote; once you approve, we agree the schedule together.

Can I get more than one design proposal for my bathroom?

Yes. Based on your habits and taste, we offer different finishes and layouts with tiles, Italian decorative plaster, wallpaper or micro cement. You can also see decorative plaster and wallpaper samples at our Erdeco store in Esenyurt.

Can Italian decorative plaster be used instead of tiles in a bathroom?

Yes, on surfaces that do not take water directly, such as basin and WC walls. It gives a seamless, silky or marble-like look; we apply it with a water-repellent top coat.

Can decorative plaster be applied inside the shower?

The inside of a shower takes water directly and constantly. There we recommend tiles or protected systems made for wet areas; decorative plaster is the better choice for walls outside the shower.

Can wallpaper be used in a bathroom or WC?

Yes, in well-ventilated rooms with little steam where water does not reach the wall; a guest WC is a good example. There we hang washable vinyl or textile wallpaper; we do not recommend wallpaper around the shower or bath.

Is textile wallpaper suitable for a WC?

Yes, in a well-ventilated WC where water does not reach the wall, textile wallpaper gives a warm, elegant look. In splash zones such as behind the basin, we finish with tiles, glass or a water-repellent decorative surface.

Can new finishes go over old tiles?

It depends on how sound the existing tiles are and on the state of the plumbing. If the plumbing is being renewed, or the tiles are hollow or lifting, they must be removed. We decide at the survey after inspecting the surface and explain why.

Is the plumbing renewed in a bathroom renovation?

Yes, where needed. We lay supply and waste lines for the new layout and prepare concealed mixer, in-wall cistern and wall-hung toilet connections. We advise against leaving old, worn pipework under a new finish.

Are the bathroom electrics done safely?

Yes. Our specialist team runs lighting, socket, towel rail and extractor lines with wet-area safety in mind. The positions of the electrical points are decided with you at the design stage.

Why is floor waterproofing important in a bathroom?

Waterproofing stops water getting into the floor slab and the flat below. We apply it continuously on the floor and in the shower area, including corners and pipe penetrations. As it sits under the finish, it is hard and costly to repair later, so it is done carefully.

What is levelling and why is it needed in a bathroom?

Levelling prepares the floor for the finish. In a bathroom the floor must fall towards the drain so that water does not pool. Walls are also made flat so the finish sits properly.

How long does a bathroom renovation take?

It depends on the size of the bathroom, whether the plumbing is changed and the finish you choose. We give the exact schedule in writing with the quote after the survey and work to that schedule.

What determines the price of a bathroom renovation?

The floor area, the scope of strip-out and plumbing, the chosen finish (tiles, decorative plaster, wallpaper or micro cement) and your sanitaryware and fittings. After a free survey we give an itemised written quote.

Is the site survey and quote free?

Yes. The site survey, measurements and written quote are free across Istanbul.

Do you supply the materials?

We can supply the materials, or we can work with products you have chosen. Either way, we check together that the products are suitable for a bathroom.

How is the work planned if the home has only one bathroom?

We plan the schedule so you know in advance which days the bathroom cannot be used. We move quickly through the stages that allow it and tell you from the start what will be done on which day.

How do you protect the neighbours during the work?

We protect shared areas, clear rubble regularly and do noisy work at hours that respect the neighbours. Careful floor waterproofing prevents water reaching the flat below, and we follow building rules.

Do you solve mould and damp problems in bathrooms?

First we find the cause: poor ventilation, missing waterproofing or a plumbing leak. During the renovation we fix the cause, add an extractor fan if needed and use materials suited to wet areas.

What do you recommend for small bathrooms?

Light-coloured large-format tiles, an in-wall cistern, wall-hung sanitaryware, recessed niches and a glass shower enclosure make a small bathroom feel more spacious. At the survey we plan the most efficient layout for the measurements.

Can I replace the bath with a shower?

Yes. We remove the bath, adapt the waste and plumbing to the new layout and prepare the shower area with a sloped floor and waterproofing. We can also build a niche into the wall if you wish.

Do you install in-wall cisterns and wall-hung toilets?

Yes. We prepare the in-wall frame and plumbing connections for the cistern and wall-hung toilet and fit them after the finish. This gives a clean look and makes the floor easier to clean.

Do you provide a workmanship guarantee?

Yes, we provide a workmanship guarantee on our work. Its scope is stated in the written quote.

Which areas do you cover for bathroom renovation?

Our head office is in Esenyurt. We serve all 39 districts of Istanbul, especially Bahçeşehir, Başakşehir, Avcılar, Büyükçekmece, Beylikdüzü, Hadımköy, Ispartakule, İkitelli, Küçükçekmece, Bakırköy, Bahçelievler and Çatalca.

Do you renovate the kitchen along with the bathroom?

Yes. We can plan bathroom and kitchen renovation together and, if needed, renovate the whole home on a turnkey basis. Our apartment and villa renovation services cover this scope.
