Bathroom Installation in Hertfordshire

Complete bathroom design, supply and installation across Hertfordshire. We manage the entire project — from stripping out the old bathroom to laying the last tile — so you have one point of contact and no coordination headaches.

A Bathroom Renovation, Done Properly

A new bathroom is one of the most rewarding home improvements you can make — and one of the most complex to manage. It touches plumbing, tiling, electrics, waterproofing and joinery, all of which need to be sequenced correctly and completed to a high standard. Getting one element wrong can cause water damage that undoes the entire job.

We manage every stage: design, material sourcing, strip-out, waterproofing, plumbing, tiling and finishing. You deal with one team and one price from the outset. We do not use subcontractors — our own engineers carry out the plumbing and our experienced tilers handle all floor and wall tiling.

We work with leading bathroom brands and can source sanitaryware, baths, showers, enclosures and tiles at trade prices — typically cheaper than buying retail. If you have already chosen products or have a specific brand in mind, we are equally happy to install your selections.

Every project starts with a site visit and detailed written quote. The price we quote is the price you pay — we do not add to it mid-project unless you request changes to the scope.

Protecting Your New Bathroom from Hertfordshire Hard Water

At 300–400ppm, Hertfordshire's water will quickly leave limescale deposits on your new shower screen, taps, chrome fittings and tiles. Shower heads typically block within 12–18 months in very hard water without treatment. We strongly recommend considering a water softener before or alongside your bathroom renovation — it will keep your new fixtures looking pristine for years longer and significantly reduce your cleaning time.

Frequently Asked Questions

A standard bathroom suite replacement (like-for-like layout, minimal tiling) typically costs £2,500–£5,000 including labour and sanitaryware. A full redesign with floor-to-ceiling tiling costs £5,000–£10,000. A high-specification en-suite or wet room can range from £6,000–£15,000 depending on size and finish. All prices include supply, fitting, tiling, plumbing and project management. A detailed itemised quote is provided before work starts.

A standard suite replacement (same layout, basic tiling) typically takes 4–7 working days. A full bathroom redesign with floor-to-ceiling tiling takes 7–12 days. A new en-suite in an existing room takes 7–10 days. We provide a specific project timeline with every written quote, so you know exactly how long you will be without bathroom access.

We can supply all sanitaryware, baths, showers, tiles and accessories at trade prices — this is usually simpler and often cheaper than sourcing independently. Alternatively, we can work with products you have already purchased or chosen. We will advise on quality and suitability for any products you are considering. We stock and install sanitaryware from leading UK brands including Roca, Villeroy & Boch, Ideal Standard and RAK Ceramics.

Our full bathroom installations include: strip-out and disposal of the existing bathroom; tanking (waterproofing) of wet areas; all first-fix plumbing; floor and wall tiling; sanitaryware supply and fitting (bath, shower, toilet, basin and vanity unit); shower enclosure or bath screen; all chrome fittings and accessories; towel rail or heated towel rail; all second-fix plumbing connections; grouting, silicone sealing and finishing. We manage the complete project from start to finish.

Yes — en-suite additions are one of the most popular projects we carry out. We assess the bedroom layout, identify the best position for plumbing connections and drainage, and design the en-suite to maximise the available space. A typical en-suite installation takes 7–10 days. Adding an en-suite typically adds significant value to a property.

Yes. A wet room is a fully waterproofed shower room with a level-access floor and concealed drain. We apply tanking (specialist waterproof membrane) to the floor and walls before tiling, ensuring complete water containment. Wet rooms are popular in Hertfordshire for their sleek appearance and ease of cleaning. We also install level-access wet rooms as part of accessible bathroom projects for elderly or mobility-impaired residents.

Yes — tiling is included as part of our full bathroom project management. We supply tiles at trade prices or work with tiles you have chosen. We advise on tile size and format relative to room dimensions, grout colour and layout pattern. Shower areas are always fully tanked before tiling to prevent water ingress behind the tiles.

Yes to both. Heated towel rails can be plumbed into the central heating system or fitted as an electric-only unit — we will recommend the right approach for your bathroom layout. Electric underfloor heating matting is an excellent option for bathroom floors and we install this as part of the tiling process. Both additions are costed in your upfront quote.

Generally no — replacing or refitting an existing bathroom does not require planning permission. If you are converting a bedroom into a bathroom or en-suite, or adding a bathroom to a new extension, permitted development rules usually still apply. The only exception is for listed buildings, where any internal works may require consent. We will advise if any permissions apply to your specific project.

Yes — Hertfordshire's very hard water (300–400ppm) will quickly leave limescale deposits on taps, shower screens, tiles and glass surfaces. Shower heads typically block within 12–18 months in very hard water areas. We recommend considering a water softener before or during a new bathroom installation — it will keep your new fixtures and fittings looking better for longer and significantly reduce cleaning time. We can advise on the right solution for your home.

We lay floor protection on all walkways from the front door to the bathroom, use dust sheets throughout and seal doorways when cutting or sanding. All waste from strip-out and packaging is removed and disposed of by us. We clean the working area at the end of each day. The bathroom is left in a usable state where possible during the project — we will discuss access arrangements at the design consultation.

Yes. We install accessible bathrooms and wet rooms for elderly residents and those with mobility requirements. This includes level-access or step-free shower areas, grab rails and support bars positioned correctly for safe use, raised toilet seats or comfort-height toilets, fold-down shower seats and lever-action taps for ease of use. We can work alongside a local authority occupational therapist recommendation if required.
