Service overview
Bathroom Installation: what it is and when you need it
What it is
Bathroom installation covers removing the old suite, running new water and waste pipework, and fitting toilets, basins, baths, showers and taps. It can also include replacing old soil stacks and waste pipes behind the scenes.
Who it's for
Homeowners renovating, landlords refreshing rental properties, and anyone whose bathroom has old, leaking or failing plumbing.
When you need it
When the suite is dated or damaged, fittings are leaking, pipework is old cast iron or lead, you're reconfiguring the room, or preparing a property for sale or let.
Why professional help matters
Most bathroom problems start with the plumbing you can't see. Getting pipework, falls and seals right is what keeps a new bathroom leak-free for years.
The cost of waiting
What happens if it's ignored
Leaking seals and failing waste connections in an old bathroom soak into floors and ceilings below, often unnoticed until damage is visible.
Old cast iron soil stacks can crack and corrode, leading to leaks and smells.
Putting a new suite on old pipework can mean ripping out new finishes later to fix hidden problems.
Common mistakes we see
- Choosing a suite before checking water pressure suits the shower you want.
- Leaving old pipework in place behind new tiles.
- Poor waste falls, causing slow drainage.
- Not sealing around baths and trays properly.

In detail
Bathroom Installation explained
Suite fitting
We fit toilets, basins, vanity units, baths and shower trays, along with taps and showers. Whether it's a like-for-like replacement or a new layout, we plan pipe runs and waste routes to suit.
Soil stack and waste pipe replacement
Many older homes in North West London still have cast iron soil stacks and waste pipework. We remove and replace them with modern plastic systems. One customer's project involved removing a 70-year-old cast iron soil stack to roof level and replacing all waste water pipework, completed with the bathroom and outside left clean and tidy.
Bathrooms for landlords
We've fitted bathroom suites across multiple properties for the same customers. For landlords, that means a reliable, repeatable result and work done when agreed, as one Yell reviewer described.
Why homeowners choose J&L
J&L Plumbing and Heating Limited is owner-run and based in Pinner, led by Jack Webster, who has 24 years of experience in the plumbing trade. There is no call-out charge, every job is quoted free on site, and we're open 24 hours. Customers regularly mention fast response, honest advice, fair pricing and tidy, punctual work, and many use us again and again.
Pricing, quotes and payment
Because every bathroom installation job is different, we don't guess prices over the phone. We come out with no call-out charge, look at the job properly and give you a free quote on site before any work begins, so you decide with the full price in front of you, not after the bill arrives. Once the work is done and tested, you can pay by card on our card machine, in cash or by bank transfer. We're fully insured with public liability cover, and if something needs attention beyond the original job, we'll explain it and quote it separately rather than simply adding it on.
What to expect on the day
Customers regularly tell us the same things about the visit itself: we turn up when we say we will, explain what we've found in plain English, suggest the practical option rather than the most expensive one, and leave the area clean and tidy. Customers often mention Jack and Lawrence by name in their reviews.
