Bath Waste Marble Bath
Posted 25 April 2016 - 09:03 AM
It has one central drainage hole (no overflow).
The base of the marble is approx 110mm thick.
I'm thinking of fitting a shower type waste where the gunk can be cleaned out from above as there is no way of lifting the bath!
Has anyone got any reccomendations of a particular model which will do the job?

Roughly 1,760,000 J per K, or about 488 Wh per K
So to raise a 2 tonne marble bath from room temperature (say, 20 deg C) to bath temperature (say 35 deg C) will need around 7.32 kWh of energy.
That's probably double the energy needed to heat the water to fill it.
It'd make a nice storage heater afterwards, though.......................

I take it that this has been considered in the build design for the weight ?
Then there is the weight of the water and the person getting into it to consider also.
The op has asked about a waste connection folks, so wrack your brains and let's find one .

It shouldn't be a difficult fabrication job to make a top access trap, like a shower, as long as the hole is an adequate diameter. A bit of large diameter brass pipe, with a brazed on standard outlet sized pipe coming out of the side at the bottom, plus a lower flange brazed on and a thread cut to allow a machined up threaded top flange to fit, then just a lift out internal trap tube, with a brass top plate brazed to it. Have the whole lot chrome plated and it should last decades.
It's the sort of job any small machine shop could knock up in half a day, plus however long it takes to get it chromed.

cross posted with Nick saying much the same

The weight is being supported on 2no 100x100 he100b steels.
It is being "hiabed" in as soon as i get the underfloor heating down, then we will build the room around it and the roof ontop of it!

Is this the point at which someone links to the thread on boiling water taps?

All the top access ones seem to be click clack, which I don't think is ideal when the plughole is centrally located.

I'm thinking that a Belfast sink waste might do the job such as:
But I would have to replace the bolt with a much longer one, say 120mm (whereas I guess they only supply a shortish bolt)
Do you think this will work?
My other option is the attached waste from a company called Drummonds, but at £95 it seems a bit steep

It's pretty cheap for the sort of bath, IMHO. I was thinking through fabricating a top access waste with integral shower type "overflowing concentric tube" trap, accessed from the plug cap and reckoned I could make one up for around £120 in materials (machined up brass, with heavy chrome plate) plus around 10 hours labour, based on the sort of time a pretty decent jobbing machine shop could make one for.
I'd assumed you'd need a wider top access waste, given the thickness of the base of the bath and the probable inaccessibility of the the area under beneath it. If you have space for an accessible trap then things get a lot easier and cheaper.

Might be possible to use that with a remote trap?

That was £1500 new, £750 ex-demo
