I wanted to start a more detailed discussion around shower room installation in London, as it seems to be something many homeowners and landlords are considering right now - whether to modernise a property, improve functionality, or add value before selling or renting.
From what I’ve seen, installing a shower room in London can vary significantly in cost depending on several factors. The size of the space is obviously important, but layout changes tend to have the biggest impact on the budget. If you’re keeping the toilet and drainage in the same position, costs are usually more manageable. However, once you start relocating pipework, upgrading soil stacks, or adjusting floor levels, labour costs can increase quickly - particularly in flats or older London properties where access can be limited.
Another major factor is waterproofing and preparation. Proper tanking of the shower area (using a waterproof membrane system) is essential to prevent leaks and long-term structural damage. This is especially important in upstairs bathrooms or apartments, where even a small leak can affect neighbouring properties. It’s worth confirming exactly what waterproofing system the installer is using rather than assuming it’s included as standard.
Ventilation is another area that often gets overlooked. Building Regulations require adequate extraction in bathrooms without openable windows, and in London properties, this is very common. A good quality extractor fan with the correct extraction rate can help prevent condensation, mould, and damp issues over time. It may not be the most exciting part of the project, but it’s definitely one of the most important.
In terms of pricing, a straightforward shower room installation in London might start from around £3,500-£5,000 for a basic spec, but mid-range finishes (quality tiles, concealed shower valves, glass screens, vanity units, recessed lighting) can easily bring the total to £6,000-£9,000 or more. High-end designs with premium fittings and bespoke features will naturally exceed this.
It’s also worth discussing timelines. A typical shower room installation may take anywhere from 1–3 weeks, depending on complexity, drying times for plaster or screed, and whether structural or electrical upgrades are required. Rushing the job is never a good idea, especially when waterproofing and tiling are involved.
When choosing an installer in London, I would strongly recommend:
• Getting at least 2-3 detailed, itemised quotes
• Checking recent completed projects (not just photos, but reviews)
• Confirming insurance and relevant certifications for plumbing and electrics
• Clarifying who is responsible for waste removal and material sourcing
• Agreeing on a clear payment schedule tied to stages of work
A well-designed shower room can dramatically improve both daily comfort and property value, particularly in London, where efficient use of space is so important. Done properly, it’s a solid long-term investment. Done poorly, it can become an expensive headache.
Would be great to hear from others who’ve recently completed a shower room installation in London - what you paid, how long it took, and whether you’d recommend your installer.
