Back to wall toilet cistern

He could simply build a box with 18mm ply, don’t screw the lid as you will need access, and fit around the cistern. Or fix batons vertically both sides of cistern, and horizontally just above the cistern- leaving room so you can get access to the cistern, then fix 18mm ply to the vertical batons, cut a lid an place on top. Cut holes as required. Back to wall toilets can leak if not fitted correctly, take time to check for these leaks by flushing mutable times. Water can cause a lot of damage over and my not be spotted for some time

This is not hard. 1. Get one of these - https://www.ebay.co.uk/p/Roper-Rhodes-Cascade-Concealed-Dual-Flush-Cistern-TR9002/2254301790?iid=223134538323&chn=ps and something like this: https://www.showerstoyou.co.uk/roper-rhodes-minerva-back-to-wall-toilet/?gclid=Cj0KCQiAg_HhBRDNARIsAGHLV512Rph5Jp7A5XegjOsrh1ydP4pRYMz8bt0VzBp3oGIupu1XF-iom0gaAlCCEALw_wcB 2. Build a frame to house the cistern. 3. Fit it with the plumbing rerouted so you can isolate from top entry. 4. Box in with 6mm cement board (NOT plywood), tile the boxing in (MITRED tile trim to finish please!). Connect WC. 5. Scribe in the countertop and fix in place with silicone only, so if there is ever a need to access the 'gubbins' just blade through the silicone and lift the countertop off. Hope the above helps.

your best bet is to use a plumber to do this.

Hi, I can't be sure what the issue is, but one obvious possibility is the difference between the types of cistern, a lot of them these days , ( and there are so many) are close coupled , which basically means they are designed to fit flush with the toilet bowl, for aesthetics. Where as older ones were simply wall mounted, the only real difference is there is no gap between the two so it just does away with the pipes that would normally be visible. Trouble is the close ones are design to be pulled to the wall for support and not hung on the wall. Plus if you want to have any cistern boxed in, your bowl would need adjusting to allow for boxing and tiles, which then extends the length necessary on the the flush handle etc , all kind of variables, length of pipes supplied etc ??? Sorry if it seems complicated 😏😏

If you want a cistern boxed, there are concealed cisterns specially designed for. Otherways, back to wall modern cistern needs to be fixed to the wall but still sitting on the loo.

Well heres how it is it need to be the right toilet for the job and right loo for the job ..horses for courses at the end of the day

Look for a plumber or a bathroom fitter.
