Re tiling, I was advised to use a quality tiler who also fits bathroom suites, rather than a plumber who can also do tiling. Like most stuff in life, you get what/who you pay for as well, but probably can’t argue against a panel will be easier to clean than tiles.
It’s how I got into Bathroom and Kitchen fitting. I am a tiler of 20 years experience, I fancied a bit of a change after 10 years of just tiling. I got fed up of seeing jobs where the plumber had done the tiling, made a hash of it IMO and still got paid top dollar.
The tiling IS the finish and needs to be 100%.
I now do top end Bathrooms and Kitchens on contract to a local design company. 10-20k territory, they hire me because of the finish I achieve compared to others who they’ve had over the years. Tilers will set everything up in the 1st instance to make the tiling look good at the end (usually).
Back on topic, yes shower panels can look good if fitted well, they can work out quite expensive though as they save the labour from the tiling but material bill is generally higher. I charge £35m/2 for tiling inc adhesive and grout, there’s 6-8m in a normal shower enclosure. I’d charge £100 to panel it instead, so very little difference in the total bill.
The big winner is time saved, 1/2 day to panel a shower Vs a day to tile it, elimination of wet trades, and I suppose also, if you like shower panels or tiles. I’d only have panels in an enclosure, I think they look a little tacky anywhere else.
