I have just finished laying 20x20 Porcelain tiles on my bath room up-stair..
Should I use grout or caulk between the Bath Tub and the new
Porcelain tiles? *TIA

Caulk. There will be some unavoidable movement between the two, due
to temp differences, tub weight changing with water, etc. Caulk
flexes, grout cracks.
