Hello All,

I am plumbing in a new bath to under an existing powershower...(its a Victorian Terrace that once had a bath but the previous owners took out the bath and put in a double shower cubicle..boooo)As the pipework stands at the moment it is 15mm pipe that runs to the powershower and I was hoping to t-piece off this pipe and connect to the bath - is there any detrimental effects of using 15mm to plumb in the supply to the taps? - the taps are quite small bore too....HELP?...to replace the 15mm piping entirely would need a huge undertaking of tearing up the tiled floor

and re-laying 22mm pipes etc...any comments/help welcome!

Cheers!

Is it a combi boiler? Is cold water off the mains, or from a tank?

Central heating and hot water are separate - (heating is run off back boiler downstairs)...cold water is run off the tank in the loft, with the hot water boiler being supplied by a tank on top of the boiler in the bathroom...

Then you ought to have 22mm pipes, otherwise the bath will fill so slowly that it annoys the users every time. You might consider running them round the bottom of the wall with extended skirting to hide them, or just bite the bullet and redo the floor.

Thanks for the advice - I think the flooring route is the way to go!....
