Luxury bathroom and wet-room refurbishment in Romford. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms across Romford, working in the 1930s semi-detached and interwar homes that fill RM1. With over 30 years in Havering, we take the small, dated bathrooms typical of these houses and rebuild them as fully waterproofed, well-drained spaces, from compact en-suites to walk-in showers and full wet rooms.

A bathroom only lasts if the waterproofing is done properly, so in Romford homes we tank the wet areas before a single tile goes up. Whether it is a walk-in shower or a full wet room, the substrate is sealed so water cannot track into the interwar timber floors and solid walls behind. Getting this right protects the structure of these older houses, where hidden leaks can quietly cause real damage over time.
Drainage and ventilation matter just as much. We set falls correctly for wet room gullies, upgrade waste runs where the original layout was cramped, and fit proper extraction to manage the humidity that plagues small interwar bathrooms. Underfloor heating is a popular addition, warming the tiled floor and helping the room dry out. Any bathroom electrics are notifiable under building regulations, so that work is certified.
The original bathrooms in Romford's interwar semis are often tight, sometimes carved out of a small rear room upstairs. We plan space-saving layouts that make them feel larger, using wall-hung sanitaryware, walk-in showers in place of bulky enclosures, and clever storage that keeps clutter off the floor. Careful tiling and lighting choices then open the room up further without changing its footprint.
Many homeowners in these houses also add an en-suite to the main bedroom, borrowing space from a landing cupboard or an oversized room. We handle the new drainage, the ventilation and the tanking for these additions, and coordinate them with the family bathroom so the plumbing works as one system. On the generous plots of RM1 there is often scope to improve the whole first floor at once.
Romford homeowners choose GS Renovation because we build bathrooms that are properly waterproofed, well drained and ventilated, not just nicely tiled. We understand the tight, dated bathrooms of RM1's interwar semis and design space-saving layouts, wet rooms and en-suites that suit them. With certified electrics and 30+ years in Havering, the finish looks good and stays sound.

FAQ
Rates per square metre are how quotations go wrong. What decides a bathroom renovation figure for a Romford home is the structure, the access at RM1 and the reinstatement afterwards, none of which appear in a market average. GS Renovation itemises so the total can be traced back to real work. Homeowners across Havering are welcome to a free survey first. Ring 07472 424 226 and GS Renovation will explain what your RM1 property actually needs. As a rough guide, bathroom renovation in London ranges from roughly £6,000 to £20,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
Allow time for the quotation, the approvals and then the build itself. After the free survey at RM1, GS Renovation issues the bathroom renovation quotation quickly, and the Havering Council route decides how much sits between agreement and starting on your Romford home. The construction phase is programmed week by week. Ring 07472 424 226 and we will map it against a 1930s and interwar property. Nothing about a Havering start date is committed before the RM1 scope is agreed.
Because it is inspected and certified, not simply declared finished. Havering Council inspects the structural stages of bathroom renovation at your RM1 property before anything is concealed, and the completion certificate is handed to you at the end. GS Renovation also appoints the structural engineer where the design requires one. That paperwork is what a buyer's solicitor asks for when a Romford home is sold anywhere in Havering. The Havering certificate arrives with the RM1 handover pack.
The electrical element is, under Part P, and it must be certified. Wet systems tie into the heating and engage Part L. We install and test underfloor heating before tiling at your RM1 property, and the certification goes through Havering Council with the rest of the work.
Only where planning designations apply, and internal work is often unaffected. Bathroom renovation in a listed Romford building needs listed building consent as well as Havering Council approval, and unauthorised work is a criminal offence. GS Renovation leads that application for an RM1 property. We confirm the designation before anyone spends money on drawings in Havering. Ask on 07472 424 226 which consents bathroom renovation actually needs at an RM1 property in Romford in the first place.
Yes. The compact bathrooms in Romford's interwar semis suit a wet room well, since removing a bulky enclosure frees up space. We fully tank the area, set the drainage falls correctly, upgrade the ventilation and add underfloor heating if wanted. The tanking is essential to protect the older timber floors and walls, and any electrics are certified under building regulations.
Yes, boundaries are not something we price against. Bathroom renovation runs across Havering and into East London, so an address on the edge of Romford or over towards Hornchurch is no harder to service. GS Renovation will say plainly if travel makes it impractical. Ring 07472 424 226 with the RM1 postcode and we will confirm. The survey that follows is free and carries no obligation. Aftercare is no more difficult a few streets further out.
