A bathroom needs to work hard every single day, which makes getting the layout, fittings, and finish right just as important as how it looks. Whether you’re after a complete redesign, a modern wet room, or a straightforward like-for-like replacement, a properly installed bathroom makes a genuine difference to your daily routine and to the value of your home.
Core Rock Ltd designs and installs bathrooms across all 10 boroughs of Greater Manchester, managing every stage from initial design through to plumbing, electrics, tiling, and final fitting. We do not subcontract. The same directly employed team that measures up your bathroom is the team that installs it.
From compact en-suites and family bathrooms in older terraces to larger main bathrooms in detached and semi-detached homes, we work with the space you have, advising honestly on layout options and what’s realistically achievable before any work begins.

From initial measuring and design through to final installation, we manage the complete process, including suite, tiling, plumbing, and electrics.

Level-access wet rooms designed and tanked properly to prevent water damage, ideal for modern bathrooms or for improving accessibility within the home.

Not ready for a full strip-out? We can update existing bathrooms with new tiling, a replacement suite, or improved fittings without a complete renovation.

All plumbing and electrical work for your bathroom is carried out in-house by qualified, certified tradespeople, including new pipework, extractor fans, lighting, and shower installations.

Full wall and floor tiling, along with proper tanking and waterproofing in wet areas, completed as part of a fully coordinated installation.

Costs depend on the size of the bathroom and the scope of work. A straightforward like-for-like bathroom refit typically ranges from £3,500 to £6,500, while a full redesign including a wet room or significant layout changes can range from £7,000 to £14,000 or more. We provide a detailed, itemised quote following a free design consultation.
A wet room has a level-access, fully tanked floor with no shower tray or enclosure, creating a seamless, open shower area. A standard shower room uses a tray and enclosure. Wet rooms generally require more extensive waterproofing work but offer a more modern look and easier accessibility.
Most bathroom installations take between one and two weeks, depending on the scope of work and whether any structural changes or wet room tanking are involved. We’ll give you a clear timeframe as part of your written quote.
If it’s your only bathroom, there will be a period without full use, particularly during plumbing disconnection and tiling. We plan the work to keep this as short as possible and can discuss options if you only have one bathroom in the property.
