Need advice on crack between tile floor and tub

The crack open up gradually over a couple of years after we bought the house. The house was a "spec-house" that we bought new. The crack is 3/4 inch wide. The tile appears to have been laid on top of a backer board which is on top of a plywood subfloor. The crack goes all the way down to the plywood.
I will attempt to post a picture.

Greetings and welcome to the forums...

I see rush tile install that used grout as the place holder between the off cut tile and the tub. What you need to do is go to a tile store and fine a flexible non-sanded caulk that matches the color of the grout that is in-between the tile on your floor. A flexible seal between the grout and the tub will cover the gap you are noticing.

Thanks for quick reply. Did you mean flexible non sanded caulk or flexible non sanded grout? I thought about both, but was concerned about the width of the gap.

Flexible non-sanded color matched "CAULK" that is manufactured by the same company that makes the grout. NOT GROUT. Get some color charts to determine the color grout you have and obtain one tube of the matching grout. There are several grout manufacturers so don't rely on just one chart. Visiting a tile store will usually find your solution quicker than going it on your own.

Ok. Thanks for clarification. Gap is entire length of tub. It is an inch deep and 3/4 inch wide. Seems like a lot of caulk.

It is an 3/4" wide because of poor craftsmanship on the install and the use of grout against the tub which has cracked out. Use blue painters tape to outline a straight line both on the floor and on the tub. That way when you smear the caulk, you will not get it all over everything. Tape, apply, spread with finger, and remove tape leaving a clean line on both surfaces.
