Bathroom Renovations by RCB Design & Build

A bathroom renovation adds comfort, value, and daily enjoyment to your home. RCB Design & Build handles the full scope — strip-out of the old bathroom, re-routing plumbing, waterproof tanking, tiling, underfloor heating, and installation of your chosen sanitaryware. Tiles, sanitaryware (bath, shower, basin, toilet), brassware, and accessories are client-supplied (second-fix materials), giving you complete control over the look and budget. We do not install carpet — RCB removal only.

Common Questions

BATHROOMS FAQ

How long does a bathroom renovation take?

A standard bathroom renovation takes 2–3 weeks from strip-out to completion. Wet rooms and en-suites built from scratch (new partition walls, drainage) can take 3–4 weeks.

Do you supply the tiles and sanitaryware?

No — tiles, sanitaryware, brassware, and accessories are client-supplied. This means you choose exactly what you want from any supplier at any price point, with no builder markup. We install everything you purchase.

Can you install underfloor heating in a bathroom?

Yes. Electric underfloor heating mats are installed beneath the floor tiles as part of the renovation. We recommend this for bathrooms and wet rooms as it eliminates the need for a radiator and keeps the floor warm.

What is waterproof tanking and do I need it?

Tanking is a liquid or sheet waterproof membrane applied to the walls and floor before tiling. It is essential in wet rooms and shower areas to prevent water penetrating the structure. We tank all shower enclosures and wet rooms as standard.

Do you install walk-in showers?

Yes. We install walk-in showers, shower enclosures, over-bath showers, and wet rooms. We fit the tray (or create a level-access wet room floor), tile the walls, and connect the shower valve and screen you have chosen.
