Just had a new shower installed, tiles going down and

Contractor "sealed" the tile/base connection with grout,
which soon cracked due to weight in shower and flexibility

cracked. How can I seal this small gap in a way that will not
crack? Or maybe I should not worry about it (concrete
backboard behind tiles). TIA

I'd get the contractor to fix it. I don't like the idea
that the base flexes so much. I'm no expert but maybe
there should have been a solid mud base under it. It can
take many months for leaks to develop if the job was not
done right in the first place.

Yeah, I'd agree with you but his descrip made it sound like a LOT of time
has passed and he's also tried to make fixes of his own, which likely
negated any warranty. He'd most likely have a losing battle on his hands
there unless it was a really pro-attitude contractor.
And you're right; there should never be any space under a shower pan,
regardless of the circumstances. It can even crack the cement over time. I
learned that the hard way on our last home.
