Bathrooms & wet rooms
Bathroom and wet room installation
From a single tap swap to a full bathroom or a fully waterproofed wet room, fitted end to end by one local team.
A bathroom is the room where poor workmanship shows up fastest. Get the waterproofing, falls and pipework right and it looks good and stays dry for years; get them wrong and you find out through the ceiling below.
We fit complete bathrooms — strip out, first fix plumbing, waterproofing, tiling, suite installation and final connections — as well as wet rooms with level-access showers, which are ideal where step-free access matters.
We can also add underfloor heating while the floor is up, replace a bath with a walk-in shower, or simply refresh taps, a shower or a basin without a full refit. Tell us the budget and we'll tell you honestly what's achievable.
Wet room or shower room?
Start with how you want to use the space: a level-access shower, a bath-to-shower conversion or a refresh of the existing fittings. The choice is not just about the finished appearance. Waterproofing, drainage falls and the arrangement of the pipework belong in the conversation before fitting starts. Our wet room versus shower room guide compares those approaches. If you are still planning the wider project, the bathroom plumbing guide gives you questions to bring to us about the layout and connections. We can then discuss the work you actually need and provide a clear quote.
If the bath barely gets used, our bath to shower conversion page explains how we swap it for a walk-in or level-access shower. Adding a WC elsewhere in the house? Our downstairs toilet installation page covers drainage, ventilation and making a compact space work.
