Yeah it’s the only shower.

I did see that on the Lowe’s website so that’s good they sell them in kits.

I attached the listing for the product I’m hoping to use so double check any material answers I give.

Pretty sure it’s fiberglass

Tub is fiberglass as well (current one and replacement one)

Tub is being replaced

Currently no shower door

I would like to do a glass shower door

House was built in 1981

If plumbing needs replacing yes

Not sure about the replace all question

I’ve done a few projects at my house, garbage disposal and dishwasher replacement. Toilet replacements, laminate floor installation. Tool wise I have a pretty well stocked garage from miter and table saw to drills drivers etc.

Edi: the listing
Via 32-in x 60-in x 80-in White Bathtub and Shower Combination Kit (Right Drain) https://www.lowes.com/pd/MAAX-White-60-in-x-32-in-x-80-in-Bathtub-Shower-Kit/5001603959

I can get some extra hands for lifting but mainly it’d just be me. How long did yours take? It’s our only shower and I’d hate for my wife to be without one for more than a few days. I can always hose off

There’s a soft spot in the floor of the tub now and I’m afraid of what’s under it and that I won’t be able to fix it and then we’ll be out of a shower.

The step that has me most worried is setting the drain properly. Everything else seems more or else something I’ve done before (leveling the floor and securing the tub)

Yeah I see what you are driving at. This sounds like the first approach I’ll take before redoing the whole room

If I’ve got multiple places with these gaps am I looking at essentially redoing the whole floor?

No I installed it right from the store, but I checked the instructions and it said that was ok.

Edit: this is the product I used Lanier Hickory 12-mil x 5-in W x 48-in L Waterproof Interlocking Luxury Vinyl Plank Flooring (18.35-sq ft/ Carton) https://www.lowes.com/pd/SMARTCORE-11-Piece-5-in-x-48-03-in-Lanier-Hickory-Luxury-Vinyl-Plank-Flooring/1000844538
