If you want a small addition that can improve your bathroom in a big way, consider buying and installing a bath fan. This will reduce humidity in the room, eliminate odors and remove moisture from the air. If you already have a bath fan and the wiring is in place, then you can expect to pay a very reasonable $150 for the installation work. If there is no current space for the fan, however, your cost might be closer to $800.
One of the most common parts of a bathroom remodel is removing the old flooring and installing new flooring. The biggest factor in the cost of this project will be the flooring itself, which can vary wildly in price. The most expensive materials are typically natural stone tiles and upscale porcelain tiles. The cheapest options might be laminate, vinyl or budget ceramic tiles. Installation can be done as a DIY project to further reduce costs, but you may need to rent or calculate how much tile or wood you'll need in order to complete the job. Expect an average cost of $2,995 to replace and install the flooring in your bathroom.
As I contractor if I am installing a customers product or supplying my own, I am charging full overhead and profit above the install cost. I try not to allow customers to supply materials and when they do I tack on my overhead and profit in to the labor. Remodeling is one of the most time consuming services and if your not covering your overhead and profit in the materials and labor you will not last long in this business. At the end of the day after all said and done, making a 15% profit is respectable. Think about it, your the designer, the gofer, the physiatrist, the builder, shopper and the banker until you get paid. Never be intimidated to support your price, deliver a quality product and support it with proper pricing. Never let the customer supply there own materials. Movie theaters don't let you bring in your own pop corn, so why should contractors be any different.
The more luxurious the materials for a bathroom remodeling project, the higher your budget will be. Using marble for your counters, custom cabinetry or handpainted ceramic tiles for your new shower walls in the master bathroom will look terrific. But it will also raise your material costs considerably more than installing a laminate countertop and low-end or mid-range tiles.
