Renuity installs bathroom remodeling solutions for Knoxville homeowners: tub replacements, walk-in tubs, walk-in showers, and tub-to-shower conversions. Licensed and insured teams handle each project within the existing tub or shower footprint, with no structural modification required. Most installations are complete the same day they begin.
Knoxville homes range from century-old properties in the city's historic neighborhoods to newer construction across Knox County's expanding suburbs, and bathrooms across that range tend to reach the same point: surfaces and fixtures that partial updates cannot fix. The Tennessee River valley's humidity puts sustained pressure on tile installations throughout the area, shortening the service life of grout-dependent surfaces beyond what age alone would predict.
Renuity replaces those surfaces with stylish upgrades, and offers walk-in configurations for homeowners whose needs have shifted.
Shower replacement installs a nonporous acrylic wall panel system and reinforced base in place of the existing tile surround and shower floor. For Knoxville homeowners dealing with a surround that has been under Tennessee Valley humidity for years or decades, the acrylic system delivers a surface with no grout lines and no porous material for that moisture to act on.
Bathtub replacement is the right project when the tub's surface condition is the issue. New acrylic installs with matching nonporous wall surrounds, holds heat better than the porcelain or fiberglass it replaces, and holds its finish without the yellowing and surface degradation that accumulate on older tub materials over time.
Walk-in showers offer a low or zero-threshold entry with sealed acrylic panels and configurable hardware: grab bars, built-in shelving, handheld showerhead. Roll-in configurations for wheelchair access are available. The installation replaces the existing tub or shower enclosure within the same footprint.
Walk-in tubs meet ADA standards and include a watertight side-entry door, built-in seat, grab bars, a textured floor surface, and a quick-drain system. Optional hydrotherapy and air jet features are available. The unit installs in a standard bathtub space without changes to the surrounding structure.
Tub-to-shower conversion replaces a tub that is no longer in regular use with a walk-in shower in the same footprint. The entry threshold drops, the acrylic panel system requires no grout maintenance, and the space shifts to match how it is being used. For Knoxville homeowners who shower exclusively, this upgrade is your best option.
Wall surrounds are available in a variety of colors and patterns suited to the range of home styles across Knoxville, from the historic character of older neighborhoods to the more contemporary construction in newer Knox County developments. Built-in shelving, recessed niches, and updated faucet and drain hardware can be incorporated into any installation. Renuity's showers and tubs installed in Tennessee are American-made.
For many Knoxville residents, the question of how the bathroom will need to work in the coming years is one they are already thinking about. Walk-in showers address the entry barrier and can be configured around seated bathing, giving homeowners a setup that functions safely as mobility changes without requiring a move.
Walk-in tubs suit homeowners who want to continue full-body bathing: the side-entry door and ADA-compliant seating make that practical on a daily basis, and the quick-drain system limits the time spent waiting for the tub to empty before exiting. Optional hydrotherapy and air jet features are available. Both options fit within the existing footprint and are available across the full color and pattern range.
The Tennessee River valley keeps Knox County homes at elevated ambient humidity through the warm months and well into the shoulder seasons. That consistent moisture is what the tile grout in older Knoxville homes has been absorbing for years. Grout is porous and takes in that humidity continuously: the result is staining that deepens over time, mold development in the joints that cleaning manages but does not resolve, and eventual cracking that opens a pathway for water to reach the wall framing behind the surface.
Acrylic wall panels have no grout and no porous surface for that moisture cycle to work against. The panels resist mold and mildew without chemical treatment, hold up under scratching and chipping with daily use, retain heat better than porcelain or fiberglass, and clean with mild soap and water. Reinforced acrylic bases carry those same properties to the tub or shower floor, where moisture exposure is most concentrated.
Renuity holds the 2025 Guildmaster Award, earned through post-project homeowner surveys measuring satisfaction and recommendation rates across completed projects. Every Knoxville installation is backed by a lifetime transferable warranty on both product and labor, with a licensed and insured team managing each project from the estimate through the finished walkthrough.
Renuity also installs replacement windows in Knoxville and handles kitchen cabinet refacing, both available through the same in-home consultation. Free in-home estimates are tailored to your project.
A Renuity consultant visits your Knoxville home, measures the tub or shower space, and presents the configurations and finishes that fit your specific layout. A complete no-obligation estimate is provided at that visit before any decisions are required.
Once you are ready to schedule, installation is booked around your availability. The crew arrives, removes the existing fixtures and surround materials, installs the new acrylic system, and handles all cleanup before the final walkthrough. Most Knoxville bathroom projects are done the same day.
