Bathroom tiling dot and dab

[Mark parry]

Hi I need some help I am having my bathroom tiled onto plaster board my tiler has put them on with dot and dab 45x90 tiles is this ok and also puting underfloor heating mat down with 45x90 tiles dot and dab my understanding it should be total coverage on floor tiles.
The pic is one of the tiles that was loose and he redone it today I queried dot and dab on the floor but he said it is because of the underfloor heating.
Any help appreciated

No he wasn't the cheapest but most expensive of the 3 qoutes i had but it was the bathroom fitter I picked and the tiler works for him.

What made you go with the most expensive?

Shouldn’t be dot and dabbed,it needs re doing .
Problem is he will do this on every job he goes on ,and I bet the finish looks decent when everything is fitted ,customers will not know the difference .
Have you pics of the full room

Probably forums where people say ‘pay peanuts get monkeys’

He was the only one that took a interest and had decent product brochure unlike the other 2 who didn't look interested.
