Frequently Asked Questions

What is a rough-in box?
A rough-in box (also called a build-in box or installation box) is the concealed part of a shower valve system that is installed within the wall during the build phase — before tiling. It houses the valve body and provides the water connections. The trim kit (handles, plate, outlets) is fitted afterwards as the finish set.
Is the trim kit included?
No — this is the rough-in box only. A compatible Grohe Rapido finish set is required for final installation and is sold separately.
What wall types is this compatible with?
This rough-in box can be installed in solid walls (brick, block, concrete) and dry cladding (plasterboard/stud walls). Appropriate fixings for both wall types are included.
What does the flushing plug do?
The pre-mounted flushing plug allows the pipework to be flushed through before the final trim kit is fitted, removing debris from the system without risking damage to the valve components.
Can I order if the item shows as out of stock?
Yes — we can still accept your order even if the item shows as out of stock. We will fulfil it as soon as stock becomes available. If you have any questions about lead times, please contact us at customerservice@bubblegumbathrooms.co.uk.
