Luxury bathroom and wet-room refurbishment in Hornchurch. Trusted, professional, 30+ years' hands-on experience.
GS Renovation renovates bathrooms across Hornchurch, from family bathrooms in 1930s semis to new en-suites and wet rooms in interwar houses throughout RM11. With more than 30 years in Havering, we handle the waterproofing, drainage, ventilation, tiling and heating as a complete job, so the finished room is watertight and built to cope with daily use.

A wet room or a level-access walk-in shower is a popular upgrade in Hornchurch, whether to modernise a dated bathroom or to make one that works long term. These installations only succeed if the waterproofing is done properly, so we tank the floor and walls, form the falls to the drain and seal every junction before a single tile goes on. Skipping this stage is the usual cause of leaks in older houses.
Interwar houses often have solid or suspended timber floors that need the right build-up to take a wet room, along with drainage that has to be rerouted to suit the new layout. We upgrade extraction so moisture is removed rather than left to damage plaster, and we handle the notifiable electrics for showers and heating under building regulations. The result is a wet room that stays dry outside the shower zone.
Adding an en-suite to a Hornchurch bedroom, or reworking a small original bathroom, is largely a question of clever planning. In interwar houses we borrow space from a landing, an oversized bedroom or a redundant airing cupboard, then design the layout so the door, basin and shower do not fight each other. Wall-hung fittings and a slim shower enclosure free up floor space in a tight room.
We finish these rooms to last, with underfloor heating for warmth without a bulky radiator, quality tiling laid on properly prepared surfaces, and ventilation sized for the space. Plumbing and drainage are reworked to reach the new position, and the electrics are certified under building regulations. Because internal bathroom work needs no planning permission, the focus stays entirely on getting the waterproofing, layout and finish right for your specific house.
Hornchurch homeowners choose GS Renovation because we get the parts that fail hidden right, tanking, drainage and ventilation, before any tile is laid. We plan space-saving layouts for interwar rooms, install underfloor heating and certify the electrics under building regulations. With 30+ years across RM11 and Havering, you get a watertight bathroom finished by one reliable team.

FAQ
By surveying first and writing it down afterwards. A Hornchurch property is measured, the structure is confirmed, and the bathroom renovation scope is agreed before GS Renovation puts a figure to it. The quotation then splits into structure, services and finishes, with the Havering Council fee visible rather than bundled. Homeowners around RM11 can hold us to it, because it is in writing. Ring 07472 424 226 or email info@gsrenovationltd.co.uk to book the RM11 visit. 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.
Longer than the build alone, because approvals come first. A bathroom renovation project at an RM11 address needs the engineer's design where the structure requires it, then a Havering Council application, before the Hornchurch programme begins. GS Renovation runs those in parallel wherever possible. The survey costs nothing and is the quickest way to get real dates in Havering. Ring 07472 424 226 and we will explain which Havering Council route suits your RM11 property best.
That is the engineer's work, not ours. We are a contractor: for a bathroom renovation job at a Hornchurch address GS Renovation arranges the engineer, the temporary works and the Havering Council approval, then constructs exactly to the issued design. You receive the calculations for the RM11 property as part of the record. It is the document a buyer's solicitor will want. Ask on 07472 424 226 about Havering projects. That separation is what protects a Havering homeowner legally.
Usually yes, and it is one of the commonest upgrades we make in Hornchurch. The constraints are the soil stack route and the floor structure, both checked at survey, and the electrics need Part P certification through Havering Council.
They make the job more interesting rather than more difficult. What bathroom renovation needs in Hornchurch is proper investigation before anything structural is touched at RM11, and an engineer's design where the load path is changing. GS Renovation coordinates that as standard. Over 30 years of hands-on experience is mostly knowing where to look in Havering. Ring 07472 424 226 and we will explain how bathroom renovation is planned in an RM11 house in Hornchurch.
Yes. The key in an interwar Hornchurch house is proper tanking, correct floor build-up and reliable drainage, which we handle before tiling so the room stays watertight. We upgrade the extraction to remove moisture, reroute the waste to suit the layout and certify the shower and heating electrics under building regulations. No planning permission is needed for an internal bathroom, so we focus on getting the waterproofing right.
Just ask, and expect a straight answer. GS Renovation works across Hornchurch, Romford and much of East London, so most enquiries about bathroom renovation at an RM11 address are within range. Where they are not, we will say so and often suggest someone else. Email info@gsrenovationltd.co.uk with the postcode and the job description. Nothing is owed for the reply or the survey. Turning work down honestly is better for a Havering homeowner than guessing.
