Freestanding bath, plumbing in the waste from underneath

Please don't do a raised platform, it's so
obviously contrived. 

Boxing the pipe in on the ceiling beneath isn't ideal but it's certainly less visually and physically intrusive. 
 

Contriving steps up really undermines the point of a freestanding bath.  The short photo you show is incredibly contrived.  Where do those three pendant lights hang in reality?  

Don't you just love these designer photographs?  Bathrooms 20 feet square, and kitchens even larger.

Also, that freestanding has dimensions smaller than a regular bath.  I'd normally
opt for 1800 x 750 where possible. 1700x700 as a minimum.    

Internal dimensions of 1000 X 480 is tiny. It will increase as the bath gets taller, but that bath is about what it looks like, not how comfortable it is to use.

worth checking what you already have and comparing how it might feel. 

Our free standing bath is 1660x800, with internal dimensions of 1150x500. It's still too large internally my for wife to sit/lay in comfortably with the shape of the bath (she's average UK female height at 5ft 3), and probably needed to be a different shape internally to make it more comfortable. 1000 internal length would have more suitable for her.

We did try out the larger version in the showroom which was obviously too big), but they didn't have the smaller version to try out. Nothing beats actually getting in one to try it out, and I wish we had searched around for one to try out before buying.

We went to a holiday cottage last year where the freestanding bath was built on a raised platform. The platform was only just 100mm bigger than the bath which made it also impossible to step into or out of the bath safely - you either had to stretch out past the platform and risk doing the splits, or try and balance on the small lip.

Ours is the larger one, I've tried taking a look at nearly all of the baths on victoriaplum and a few other sites and they seem to all have fairly similar internal dimensions, but happy to take any recommendations. Our current bath is only 370 wide at its lowest level rising to 520 at the top so I think it's a decent upgrade. Current length is 1200mm at the shortest rising to 1500 at the top so length is about the same at the base.

Joists can be drilled , it’s common practice . Obviously caution has to be taken , theres a few guides online that show joist depths and max permissible hole that be cut from wall edge 

Notching of joists is a definite no

... and reinforced if needed.

A joist is like a girder. The strength is in the top and bottom. That’s why a classic girder shape has a capital I construction. So, yes, a hole through the middle of a joist won’t harm its strength nearly as much as a notch in the top.

But, it’s far far easier to make a notch in the top.

Sometimes its necessary to drop the waste down and run at ceiling height in the room below and have it boxed in, done a few 

A builder is mentioned any mention of a plumber doing the plumbing work just mentioning that as some baths exceed 230 liters and need notification  

Nice looking bath from the photo

This is the current bath in place, its quite small and not very wide at the narrow end, and at the deep end you have the taps so cant really use that end for anything other than standing. you can see the boxing slightly on the left hand side in white but in more detail in next photo



Current waste leads to that bit of wood boxing. The new bath is 800mm wide, the waste position ends up being pretty much bang on where that current one is, but its in the middle of the bath, not up that end. 


This is our hallway below - the part that sticks out on the left hand side is our soil pipe. The builder proposes boxing in an extra element at the end, above the door, so waste would drop down, along to the end of the joist and then down into this new boxed in area and connect to the soil pipe. 




I was a bit worried about the distance because the bath wont be directly above where that part is in the hall, part of the bath's footprint will be over the kitchen wall & into the kitchen (on the right hand side of the front door) - the above photo shows the distance from the wall in the bathroom to where the waste will be positioned, so its pretty much right above the kitchen wall - will that cause any complications? guessing the wall wont go up through the floor? no boxing could be done in the kitchen itself, because there is a cabinet right next to that wall. For clarity, where the start of bannister is at the bottom right of the photo is just slightly proud of the wall to the right of the front door in the above image. 

The original bathroom is falling apart as previous owner did everything on the cheap - VictorianPlumbing shower that leaks, rainfall taps that overshoot the sink, flooring is the cheapest vinyl but no underlay or ply so its cracked in about 700 places, and the "tiled" wall is really PVC panel made to look like tiles. We cant wait to be shot of it, but also want to make sure its done right to avoid any future issues

The waste on your new bath is off centre, and you can have the waste on the side nearest the centre of the room. Have you allowed for that?

Will the taps be wall mounted?

I have a nasty feeling that these baths will look as dated as avocado suites in a few years time. Yet, there was a time in the 70s when every new build had an avocado suite.

These free standing baths are not very practical. They use huge quantities of water. Water can splash out in all directions. There are awkward gaps where you can’t clean. External taps mean that any drips won’t go in the bath. To get to the plumbing you may need to remove the entire bath. I could go on ….
