You could also consider tanking the shower before tiling (a good installation would do this anyway). Then you aren't relying on tiling to be watertight which is always a gamble anyway.

They certainly exist! The choice is overwhelming though and you might want to narrow it down a little by deciding what style to go for. Perhaps you can start by looking at designer houses like Vitra. These come in a certain price bracket but you can always check Ebay and the like if you don't mind a used chair. I have a couple of Aeron (Herman Miller) chairs in my work room. I think they're stylish, but more in a functional than aesthetic way perhaps.

Yes I get what the idea was - but it would probably eat into the air gap requirement for the FF … and could cause it to overheat… alternatives could include a drop down tv from ceiling (or small one under wall cabinet ) - obvs in a place where it won’t be walked into or obstruct cupboards when it’s down. Or an iPad on a cook book stand could suffice too ?!
