Aging in place: Finding the right walk in shower for your bathroom Remodel| O'Fallon, MO|Just Bathrooms 636

Everything homeowners across O'Fallon, St. Charles, St. Peters, Cottleville, Wentzville, Lake St. Louis, St. Louis, Chesterfield, and the surrounding area need to know before installing a walk-in shower:  cost, sizes, seats, doors, colors, and the brands we trust, including Kohler and Onyx.

Quick Answer: A professionally installed walk-in shower typically costs $6,000–$15,000, with most St. Charles County homeowners landing near $9,000–$12,000 for a mid-size project. A basic prefabricated kit swapped into an existing tub space can start around $3,000–$5,000. Fully custom tile-and-glass showers with a seat, bench, or premium solid-surface walls like Onyx typically run $15,000–$25,000+. The three biggest cost drivers are shower size, whether the drain or plumbing has to move, and the wall/floor material you choose.

What Is a wALK-IN SHOWER?

A walk-in shower is a shower with no tub wall or high curb to climb over. You step directly in from the bathroom floor, usually onto a low-profile or fully curbless base with a gentle slope toward the drain. Depending on the design, the shower is enclosed with a glass panel or door, left completely open, or fitted with a shower curtain on a straight or curved rod.


Walk-in showers have become the most requested upgrade in bathroom remodeling because they solve three problems at once: they're easier and safer to enter, they make a small bathroom feel larger, and they modernize the look of an outdated tub-shower combo.


wALK-IN SHOWERS FOR SMALL BATHROOMS

You don't need a large bathroom to get a walk-in shower. A well-designed walk-in shower can work in a footprint as small as 36" x 36", and 36" x 48" gives comfortable room to move and turn. The trick in a tight bathroom is choosing the right enclosure:


Glass Panel, No Door

A single fixed glass panel keeps splash contained in a small footprint while keeping the room feeling open — a common pick for compact hall bathrooms.


Sliding or Pivot Door

Doesn't require the swing clearance of a hinged door, which matters when floor space is limited.


Corner Neo-Angle

Fits into an unused corner and can be one of the most space-efficient layouts for a small full or half bath.


During your in-home consultation, we lay out your exact bathroom in 3D before recommending a size or configuration, so there are no surprises once demo starts.



AGING IN PLACE: WHY WALK IN SHOWERS ARE THE BEST CHOICE FOR SENIORS

Walk-in showers are one of the highest-impact upgrades for aging in place safely, and it's a large share of the remodeling work we do throughout O'Fallon, St. Peters, and St. Charles County. A shower built for long-term safety typically includes:

  • Zero-threshold or low-curb entry — removes the single biggest fall hazard in the bathroom
  • Built-in or fold-down seat — lets you shower seated without a separate shower chair
  • Handheld showerhead on a slide bar — usable from a seated or standing position
  • Grab bars anchored to wall blocking — not suction-mounted, rated to support real body weight
  • Slip-resistant flooring — textured tile or solid-surface pan finish
  • Wide entry (36"+) — clears a walker or wheelchair comfortably


Does Medicare pay for a walk-in shower? Original Medicare typically does not, since it's classified as a home modification rather than durable medical equipment. Some Medicare Advantage plans, VA home improvement benefits, Medicaid HCBS waivers, and USDA Section 504 rural grants can help offset the cost. We provide the itemized quote most of these programs require.

Doors, Doorless & Shower Curtains

One of the first decisions in any walk-in shower project is how , or whether to enclose it.

A fully open, doorless design is the cleanest modern look and the easiest to keep accessible, but needs a larger footprint and careful showerhead placement to control splash.

  • What is the average cost to put in a walk-in shower?

    Most homeowners spend $6,000–$15,000 for a professional installation, averaging around $9,000–$12,000. Basic kits start around $3,000–$5,000; fully custom builds run $15,000–$25,000+.

  • What are the disadvantages of a walk-in shower?

    Less built-in water containment than a curtained tub if undersized, loss of tub/soaking functionality if it's your only bathtub, higher upfront cost than a simple liner, and a possible resale consideration in markets where buyers expect at least one tub. Correct sizing and enclosure choice address most of these.


  • Does Medicare pay for a walk-in shower?

    Usually not under Original Medicare, since it's considered a home modification rather than durable medical equipment. Some Medicare Advantage plans, VA benefits, Medicaid waivers, and USDA rural grants may help.

  • Should I choose a walk-in shower with a door, or go doorless?

    Doorless designs are the cleanest, most accessible look but need more floor space. Glass doors or panels contain water better in smaller bathrooms. Shower curtains are the lowest-cost option, often used on doorless frames.

  • What is the best walk-in shower for seniors?

    One with a zero-threshold entry, a built-in seat, a handheld showerhead on a slide bar, wall-anchored grab bars, slip-resistant flooring, and a wide entry of at least 36 inches. Solid-surface (Onyx) and acrylic (Kohler) systems are popular choices for aging-in-place.

  • Are Kohler or Onyx walk-in showers better?

    Both are excellent; Kohler's LuxStone and Choreograph lines offer wide color/hardware options, while Onyx's solid-surface systems are prized for a seamless, low-maintenance finish. We install both and will recommend based on your layout and goals.

  • Can I install a walk-in shower kit from Home Depot myself?

    For a simple, same-footprint swap it can work, but most conversions still require subfloor waterproofing, correct drain slope, and code-compliant plumbin,  the parts that determine whether the shower lasts or leaks. Professional installation includes labor and materials warranties.

  • What size walk-in shower works in a small bathroom?

    As small as 36" x 36", though 36" x 48" or larger is more comfortable. Doorless designs need extra adjacent floor space to control splash. A 3D layout during your consultation confirms exact fit.

  • What colors are walk-in showers available in?

    White and light gray remain the most popular for resale value; black and dark tones are trending for a modern, spa-like look; silver/nickel hardware and green accent tile show up most often as feature elements.

  • Is a steam shower a good idea?

    For homeowners interested in relaxation and light respiratory or muscle benefits, a steam shower can be a worthwhile upgrade, especially when it's built into a bathroom remodel from the start with correct waterproofing, ventilation, and materials. It's less ideal as a quick add-on to an existing shower without addressing those requirements.

  • Is a used walk-in shower a good idea?

    We don't recommend installing a used shower system. Reused acrylic, solid-surface, or glass components are difficult to warranty, may not fit new plumbing correctly, and often show wear (cracking, discoloration, seal failure) that isn't visible until water gets behind the surface. A new prefab kit at the lower end of the budget range is a safer starting point than a used unit.
