Our Process
How Your Bathroom Renovation Works
1
Free Design Consultation
We measure your bathroom, discuss your vision and provide advice on layout, sanitaryware, tiles, and fittings. We also advise on wet room feasibility, underfloor heating, and ventilation requirements.
2
Detailed Quote
You receive a fully itemised written quote covering all trades and materials. We make clear what is included in the price and what optional extras are available.
3
Strip Out & First Fix
We remove the existing bathroom suite and tiling, make good the plasterwork, and complete all first-fix plumbing and electrical work before any tiling begins.
4
Tiling, Fit & Finish
Tiling, sanitaryware installation, second-fix plumbing and electrics, accessories, decoration and sealant are all completed to a high standard. We leave your bathroom clean and snagging-free.
