Getting rid of that cramped tub for a clean, open walk-in shower changes your morning routine entirely and makes the whole bathroom feel twice the size. A standard tile remodel usually takes about one to two weeks of actual dusty work once the crew shows up. Scheduling contractors in late winter is your best move since schedules slow down and you are much more likely to get a quick callback and a fair rate.
Before you commit to anyone, get at least three distinct quotes from local tile setters or general contractors. Prices swing wildly for the exact same square footage, and having options stops you from overpaying for labor.
Remember that the 18-month 0% window is a hard deadline and not free money, so if any balance is still sitting on the Citi Simplicity® Credit Card when that period ends, you will get hit with interest on the remaining amount.
