I have a new home plastic/fiberglass shower stall with a glass door and side panel. Two side are the plastic and it is probably 8' tall. I do not want to enlarge it at all. I want to just replace. It is like an inset that was there when we built the house. Not fancy. It is a white/cream color and I would just like something nicer to replace it. Anyone intrested in the Spring, Texas area.
Yeah, I feel your pain. I'm in Alabama, one of the lowest income states in the country, and I got a quote from a "big box" hardware store here. $39,000 -- to remodel a 9 x 12 bathroom. I won't go into the details but I'll tell you that the estimate included $3600 for electrical work. Uhh, we are simply switching out 2 'regular' outlets and putting in $20-dollar GFI outlets. The wiring is fine (I know because I've been in the wall before). So don't go to the "big box" stores unless you want the highest possible estimate (oh, yeah ... I had to pay for the estimate as well).

For yourself, having fresh flowers in the planned new bathroom is small thing that can brighten every morning. Lightening candles in the planned new bathroom is also a simple aspect whenever you get into the room feeling so tired. Taking a bath with dimly-lighted candles will hopefully put your minds at rest, brings calmness to your head thus feels so fresh after that.
If someone was to come at us with their own additional contract, we would probably decide that we had given them enough of our time and move on. As Nick mentions below, the contractors reputation is the one on the line. They have every reason to do right by you. The crooks of the world generally don't have a reputation to stand on, and as a customer it is your job to research who you are hiring. If you can't find anything about them, they probably aren't who you want to be dealing with. If they ask for money upfront, they probably aren't running a stable outfit. We never take a penny upfront. We collect when the job is fully complete even when we are working on weeks long projects.
Between the two options, pick up one tile design that suits your necessity and budget. Remember to put forward safety for your children in this point. In case your budget is limited, you can partially change the tile. Determine which part of the bathroom that needs new, safer tiles. This will definitely save more money compared to overall tile changing.
