GS Renovation renovates bathrooms across Westminster, from Regency townhouses in Belgravia to period mansion flats in Marylebone and Pimlico. With more than 30 years in W1, W2, SW1, WC2, NW8 and W9, we handle full waterproofing, drainage, tiling and heating, fitting wet rooms, en-suites and space-saving layouts that work within the borough's tight period footprints.
Waterproofing and wet rooms in Westminster
A bathroom in a Westminster townhouse or mansion flat almost always sits above another room or another home, so waterproofing is where we start. We fully tank walls and floors before tiling, form falls correctly for walk-in showers and wet rooms, and make sure drainage and ventilation are properly designed to protect the period fabric below. Done right, this is what stops leaks reaching the flat downstairs.
For leasehold flats in NW8 and W9, sound insulation and building-management rules matter as much as the finish. We coordinate with the managing agent on access and working hours, and pay careful attention to acoustic detailing where a bathroom sits over a neighbour. Every notifiable electrical and plumbing change is carried out to building regulations and certified on completion.
Space-saving bathrooms in Westminster period homes
Period homes in Marylebone and Pimlico rarely offer generous bathrooms, so clever layout does the heavy lifting. We carve en-suites out of awkward corners, use wall-hung sanitaryware and recessed niches to free up floor space, and plan the room around the soil stack and joist runs of a Georgian or Victorian house rather than fighting them.
Underfloor heating, warm tiling and considered lighting turn a small period bathroom into a genuine luxury. In listed properties across SW1 and W1 we work sensitively with original features and protected fabric, reconfiguring services discreetly so the finished bathroom feels contemporary without stripping the character out of the house. Every trade, from tanking to tiling, is handled by our own team.
- Concealed cisterns, frames and wall-hung sanitaryware
