I am finalising the details of the a bathroom refurb which includes a
1000x900 shower enclosure. The shower will be located against two internal walls and the floor is a concrete slab. I understand the usual way around this is to raise the shower tray using a purpose built kit or d-i-y frame and surface run the pipework - not the best result from a looks viewpoint.The only alternative would seem to be digging an 90mm deep x 3 metres long channel in the floor to meet up with the existing bath waste. A bit of googling reveals that this is frowned on by many as it may have maintenance implications. Given that shower wastes are now accessible from above which should cope with any likely blockages is there any reason not to consider this alternative?
Grateful for your thoughts.
