What Is a Full Bathroom Renovation?

A full bathroom renovation transforms your existing bathroom from complete strip-out through to a brand new finished space — new layout, new sanitaryware, tiling, plumbing and all finishing details.

Whether you want a simple, clean modern bathroom or a fully designed luxury wet room, we manage the entire project from design advice and strip-out through to final tiling, fitting and finishing.

We handle all trades in-house — plumbing, tiling, electrics and carpentry — so you deal with one team and one point of contact throughout.
