Thanks for the replies guys. The boiler is a combi but supplies at about 1.5bar. The pressure for the shower is no problem. I just hope the drain copes! Couldn't resist a quick try-out!
I wondered about pumps etc but in the end I wanted to keep it as simple as possible. This is actually a practice run before attempting the main bathroom. !!
By day, i'm an offshore helicopter pilot out of Humberside, flying guys out to the gas rigs. We work a very changeable roster system hence the days on/off I get. For instance i'm working monday, meeting in Aberdeen tuesday, off wed and thurs, in fri to monday then off for two days and then on for two. Really messes with your head.
I used to be a senior marine engineer for many years, hence being handy with soldering and plumbing and electrical work. Did an HND in electrical, electronic and mechanical engineering years ago.
Well, just wired up the underfloor heating and did a bit of tidying up as I was sitting bored and it was only 7.30pm.
Wife thinks i'm crazy.
Unfortunately I have a 6am start tomorrow so probably won't get much done in the afternoon. All of my tiles need sealing before fixing so I guess I should make a start on that tomorrow.
The underfloor heating is a no-brainer if you're doing a wetroom, in my opinion, as the room floor will always be warm and it'll help dry the floor quicker after use. Glad I did decide on it now. Unfortunately the water around here is very hard so it'll leave white marks on the tiles. Have to see how it goes and just re-seal the tiles regularly as they're travertine noce.
