A professional bathroom renovation involves far more than swapping a suite. At JBW Construction, we deliver complete bathroom transformations including plumbing upgrades, electrical rewiring to bathroom-safe standards, waterproof tanking, tiling, underfloor heating installation, and bespoke joinery — all completed by our directly-employed team. Whether you're converting a box room into an en-suite, adding a downstairs WC, or completely redesigning your family bathroom, we manage every element. Our approach ensures proper waterproofing, adequate ventilation, and compliant electrical installations — the technical details that prevent leaks, damp, and safety hazards. We work with all bathroom brands and suppliers, or we can supply complete bathroom packages at competitive trade prices. Our design advice is included free with every project, helping you maximise your space and budget. ### Related Services - Kitchen Renovations - Loft Conversions - Property Extensions - Refurbishments - Accessible Home Adaptations - Request a Quote ## What Goes Wrong With Bathroom Renovations? Water damage from poor bathroom installations is one of the most expensive remedial repairs in a home. Inadequate tanking behind shower enclosures allows water to penetrate walls and floors, causing rot in timber joists, plaster degradation, and ceiling collapse in rooms below. We install full tanking systems to BS 5385 standards on every wet area. Electrical safety is critical in bathrooms. Installations must comply with BS 7671 bathroom zone regulations — specifying exactly what can be installed where and at what IP rating. Non-compliant bathroom electrics are not just an MOT failure for your home; they're genuinely dangerous. Our NICEIC-registered electricians ensure full compliance. Drainage failures are the third common issue. Showers, baths, and basins need adequate waste pipe falls and correct trap configurations. When these are wrong, water drains slowly, traps dry out releasing sewer gases, and blockages occur. We design drainage correctly from the outset. Our Process ## How We Deliver Your Bathroom Renovation Step 1 ### Design Consultation We visit your home, measure the space, discuss your wishlist, and advise on layout, products, and budget options. Step 2 ### Product Selection Choose from our range or specify your own products. We advise on quality, durability, and value for money. Step 3 ### Strip-Out Existing bathroom removed carefully, with protection to surrounding areas. Any underlying issues identified and addressed. Step 4 ### First Fix Plumbing rerouted, electrical circuits installed to bathroom zone standards, underfloor heating laid, and walls prepared. Step 5 ### Waterproofing & Tiling Full tanking applied to wet areas, followed by wall and floor tiling with quality adhesives and grouts. Step 6 ### Second Fix & Handover Sanitaryware, shower enclosures, screens, accessories, and lighting installed. Final clean and handover.

We assess the feasibility during our initial visit, design the optimal layout, and handle all building work including partition walls, plumbing connections, waste pipe routing, and mechanical ventilation installation. ### Walk-In Showers & Wet Rooms Walk-in showers and full wet rooms are increasingly popular in Chesterfield homes. We install linear drains, gradient floors, and full room tanking to create leak-free wet rooms. Glass screens and frameless enclosures complete the contemporary look. ### Underfloor Heating Systems Bathroom underfloor heating eliminates cold tiles and frees wall space by removing radiators. We install electric heating mats for simple retrofits or connect to your existing wet heating system for larger installations. Individual thermostatic control ensures comfortable temperatures. ### Accessible Bathrooms We design and install accessible bathrooms for mobility-impaired users including level-access showers, grab rails, raised WCs, and wider doorways. We can advise on Disabled Facilities Grant applications through Chesterfield Borough Council. ### Downstairs WC Additions Adding a downstairs WC involves finding suitable drainage connections and adequate space — often under stairs or in a utility area. We handle all structural work, plumbing connections, and ventilation to create a functional and attractive cloakroom.
