  • How much to change a sink and bath in London?

    Posted by Derek Jordan on January 2, 2026 at 12:38 pm

    I bought my first Home this year in January and had a really bad experience with cowboys to the point that a bath that was perfectly fine. I’ve now got to have a placed in the sink that was fine. I’ve now got to have it replaced.  I don’t mind replacing the sink as it doesn’t fit with the tiles, but the bath is annoying.

    Anyway, I was initially going to have a vanity and sink unit, but I’ve been told that that won’t fit because of the pipe at the bottom so it’s been recommended that I have a wall hung one but my concern is the waste pipe that goes up the wall. You will see the Plumner says you won’t so any recommendations. Please feel free to suggest.

    I’m based in London. How much should I also be looking at to change a sink and bath? I’ve been quoted anything from £600-£1000 so far.

    I’m a bit confused but then I’m not very good at visualising things. Are you talking about the horizontal pipe? If so, why can’t you have the sink and vanity unit and the noticeable pipe be boxed in with tiles etc? I have that in my current bathroom and had it in my previous bathroom. If you’re talking about the vertical pipe, there’s usually space for that pipe behind the backboard of the vanity unit for the pipe work.

    tbh, I think I would get advise from another plumber. If you’re having a wall hung basin with a pedestal then you won’t see the vertical pipe as the pedestal should hide the fittings/pipe, as you can see from your picture on the right. If you’re having a wall hung non pedestal basin then yes you will see the fittings, but they don’t have to look horrendous, this is how mine looks in my shower room. However, you certainly can have a vanity unit with pipes running across the floor, as I said, you just box them in. Vanity units have a space behind the cupboard backboard to accommodate pipes. Why can’t your plumber cut holes into the sides of the cupboard at the back to accommodate the horizontal pipes, the unit will then fit snug against the back wall, you then just need to box the pipes in. I’ve had this done twice. I would go into a bathroom store & ask their advice.

    It would be much easier if you buy a vanity unit that sits on the floor, and they can box in the pipes, and cut a bit at the back of each side of the unit. It will be unseen. Your plumber is correct in what he is telling you, if you have a wall hung vanity unit and there is no way to re-route those waste pipes.

    I agree. I can’t understand why the pipes aren’t hidden in the void behind the vanity backboard and then holes are cut into the side panels either side of the unit for the pipes.

    The issue is he’s saying is I can’t have one that goes on the floor because of the pipes along the bottom it won’t sit flush against the wall.

    So he recommended instead I went for a wall hung and I’d have a tiny bit of vertical pipe showing
