The nice fiberglass ones can really hold up, I've installed 5 Sterling 4 pc surrounds in very small baths and they've been terrific, have kept pretty clean.

I considered fixing and refinishing the existing fiberglass tub but got conflicting information from refinishing companies as to the durability of the refinished product and the ability to refinish a second time.

We've lined up a majority of work in our scope and scheduled out most of it: Plumbing for a bathroom and kitchen - $3,800Crawlspace repairs to fix some prior shady work & even out some unlevel areas - $3,650Tile 2 kitchens & 2 bathrooms - $1,800Drywall repairs - $400Add railings and supports to half-finished back deck - $2,800Install 2 interior doors - $300Fix a rotted Yankee gutter and repair some cracked fiberglass cement siding - $1,8002 full appliance suites (Kitchen/Laundry) - $6,000Fix one broken window - $250Relocate three HVAC vents - $900Still, a bit to be quoted/scheduled, but so far we are below our projected rehab budget of $41,250.

I was initially going to purchase a fiberglass or steel door, but figured it would be more cost effective to just work with the door I have.

I did research and found the steel is the budget friendly door, but comparing prices between steel and fiber glass on Home Depot, fiber glass doesn't seem that much more expensive. 

Remodelers need masks to protect from fiberglass insulation, rat sh-t dust, etc.

This would be assuming a full gut, and vinyl flooring, vanity package from big box store, fiberglass tub/shower surround or shower stall, etc.

The fiberglass shower pan was installed by a "pro" ... friend of a friend who is an actual plumber.

If the water damage is getting into the next room, you may be talking lots of sheetrock work, flooring, some frame replacement and then the shower itself...... cost will vary depending on cheap fiberglass drop in or full tile etc etc....No way to comment on the cost....it may be dead on..... not enough info to comment

We dont plan on moving any walls or anything big... we do plan on tile work, countertops, lighting/fixture/hardware replacements, taking out old carpeting and replacing with LVP (vinyl plank flooring), replacement of old appliances wtih new stainless plus a moderate master bath remodel (take out old fiberglass tub/shower and make that area pop with new shower w tile and sitting tub.
