Just under 5k from me, customer supplied all the gear bar pipe, fittings, self leveller, adhesive and grout.
Plenty of assistance before hand to make sure the tray former and tanking was what I wanted. The wash stand, mirror and towel holder were all custom made, shower screens 10mm kudox, vitra basin and grohe shower, taps and wc.
First smart box shower I've fitted, very impressed.
Wall tiles were porcelain, drilling was a pain, floor tiles ceramic. All expensive and really good quality.
Warm up underfloor heating. Electrician was in for a day and half. New spots, wall lights moved, new shaver socket, under floor, electric towel rail and wifi control for underfloor.
So I would think your 10k is not far from the mark.
Nice to work with top end materials for a really good customer.
I'm out this morning to fix a toilet. Then tomorrow to strip out a shower enclosure and prime, tile monday, grout and finish Tuesday then that's it. Phone off and 10 days off.
Only blot is that overnight the wifes uncle passed away. Heart failure, but he had a positive covid test a couple of weeks ago and although he wasnt affected by it it will go down as the cause of death.
