The things that may scare someone away is agreeing on cost and deadline before they could know what they are getting into. The last thing they want is for this job to cost them money. I think a good way to talk about deadline and reimbursement it to tell them your concerns. Be honest, tell them it is costing you time and money having to shower somewhere else. Ask them if it would be possible to be reimbursed if it goes over deadline. If they agree put it in contract. What I think the trick is, is to bring up the topic and let it be their idea or have them agree to an idea rather than coming to them with something seeming like demands. Offer a drink or something, seem friendly and easy to work with. Kindness goes a long way. Their reputation is on the line not yours.
Both Lowe’s and Home Depot offer bathroom remodeling services. Home Depot remodels cost $5,000 for a powder room up to $30,000 for a master bathroom remodel. Lowe’s suggests that customers expect to pay at least $100 per square foot on bathroom remodels. Both stores offer repairs on your existing fixtures and installing upgrades or new replacement parts.
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.
