Luxury en-suite bathroom with brushed brass fixtures and a walk-in shower – Grand Innovations

Luxury en-suite with brushed brass fixtures and walk-in shower — Surrey

Your bathroom, your private sanctuary.

Your bathroom should be a sanctuary. We design and install premium bathrooms across Surrey and London, handling every element from initial concept and 3D visualisation through to plumbing, electrics, tiling and final finishing. Whether you're upgrading a tired family bathroom, creating a luxury en-suite, or converting a cupboard into a compact shower room, we deliver exceptional results.

Our bathroom work includes underfloor heating, wet room tanking, smart digital shower systems, bespoke vanity units, designer porcelain and natural-stone tiling, and concealed cistern installation. We work with leading brands including Duravit, Hansgrohe, Porcelanosa and Villeroy & Boch, and can source specialist fittings to match any design vision.

All plumbing and electrical work is carried out by qualified, certified tradespeople and fully compliant with current Building Regulations — then billed weekly against completed, signed-off work, so you always know exactly where you stand.

Bathroom Types

A bathroom for every space.

From the smallest cloakroom to a full spa-style master suite, we design and build it bespoke to your room — never off a showroom shelf.

Luxury Master Suite

Most popular

A spa-inspired retreat with freestanding bath, walk-in shower, twin vanities and underfloor heating — the bathroom you slow down in at the end of the day.

Wet Room

Fully tanked, level-access wet rooms with seamless drainage and large-format tiling — beautifully waterproof and built to BS EN 14527 standards.

En-suite

Clever, space-efficient en-suites that turn an awkward cupboard or corner of a bedroom into a private, high-specification shower room.

Cloakroom / WC

Small rooms with a big impact — concealed cisterns, statement basins and characterful tiling that make a downstairs WC feel deliberate, not an afterthought.

Accessible Bathroom

Level-access showers, grab rails, comfort-height fittings and slip-resistant flooring — designed for independence without sacrificing style.

Family Bathroom

Hard-wearing, practical bathrooms built for busy households — generous storage, easy-clean surfaces and a layout that copes with the morning rush.

Brands & Finishes

Designer brands & finishes.

The difference between a good bathroom and a great one is in the fittings and the finish. We specify and install premium sanitaryware, brassware and tiling from names that are built to last — and we install them to the manufacturer's exact specification, so they look and perform the way they should for years.

Prefer to supply your own pieces? That's no problem at all. Either way, we bring the underfloor heating, smart digital showers and considered detailing that turn a collection of fittings into a genuinely calm, cohesive room.

  • Hansgrohe brassware & showers
  • Porcelanosa tiling
  • Smart digital shower systems
  • Underfloor heating as standard

Kingston Multi-Bathroom Renovation – Grand Innovations
Case Study

Kingston, London

Kingston Multi-Bathroom Renovation

This Kingston project delivered an uncompromising, total transformation of the property's washroom facilities, successfully renovating four distinct bathrooms throughout the historic home. The downstairs WC was meticulously refreshed with calming sage green walls and elegant brushed brass fixtures. Upstairs, the main family bathroom introduces a sophisticated dark marble-effect tiling profile paired with luxurious brushed brass rain showers and waterfall bath taps.

The Challenge

Simultaneously managing the plumbing and structural overhauls of four separate bathrooms on multiple floors without disrupting the structural integrity of the historic floor joists.

Our Solution

We utilized low-profile, high-flow aquatic tracking to reroute internal drainage seamlessly, paired with rigorous acoustic insulation beneath the luxury wood-effect flooring to eliminate internal noise transfer entirely.
