The Aurora 5×8 Challenge
Most homes built in Aurora and the Denver metro between the 1960s and 1990s have the same basic bathroom: 5 feet wide, 8 feet long, with a tub/shower combo taking up one end. Removing that tub and converting to a walk-in shower is one of the most popular remodel requests we get — and for good reason. A properly designed walk-in shower makes a small bathroom feel dramatically larger and more modern.
The good news: a 5×8 bathroom gives you plenty of room for a code-compliant, comfortable walk-in shower. Here's how to make it work.
Code Minimums: What IRC P2709 and ADA Say
Before discussing design, understand the minimum sizes required by code:
- •IRC P2709 (International Residential Code): Shower compartments must have at least 900 square inches of floor area — that's a 30×30 inch minimum — with no dimension less than 30 inches. However, 30×30 is extremely tight. Aurora and most Denver metro jurisdictions enforce the IRC.
- •ADA 608.3 standard (for accessibility): Minimum 36×36 inches for a transfer shower, or 30×60 for a roll-in shower. Even if you're not building to ADA standards today, a 36×36 or larger shower is far more comfortable and future-proof.
- •Practical recommendation: Build at least 36×36, and 36×48 or larger if your layout allows. The difference in cost is minimal; the difference in daily usability is significant.
Design Tricks That Make Small Showers Feel Larger
1. Go Frameless or Semi-Frameless
Heavy aluminum-framed shower doors chop up a small space visually. A frameless glass door or a simple glass panel (sometimes called a wet wall or walk-in panel) lets the eye travel through the space uninterrupted. In a small bathroom, this single change has a bigger visual impact than almost anything else.
2. Large-Format Wall Tile
Smaller tiles mean more grout lines — and more grout lines make a space feel busier and smaller. Use 12×24 or larger tile on shower walls. Running it vertically (portrait orientation) draws the eye up and makes ceilings feel higher. A single large-format tile used floor-to-ceiling with minimal grout joints creates a spa-like, seamless look.
3. Curbless (Barrier-Free) Entry
Eliminating the curb (the threshold step into the shower) makes the shower and bathroom floor read as a single continuous surface — which dramatically expands how large the room feels. A curbless shower also complies with ADA accessibility guidelines (ADA 608.7) and is easier to clean. The floor must slope toward the drain at a minimum 1/8 inch per foot per code.
4. Recessed Niches Instead of Corner Shelves
Corner shelves and caddies stick into the shower space and make it feel smaller. A recessed niche — a box built into the wall between studs — keeps everything flush and organized without eating into your footprint. We can typically fit a 12×24 niche between standard 16-inch-on-center studs.
5. Light Colors and Reflective Surfaces
White, cream, light gray, and warm beige tiles reflect light and make tight spaces feel open. Pair them with polished or brushed chrome fixtures. If you want contrast, use a darker accent on one wall — not all four. A single dark feature wall (like a charcoal tile behind the showerhead) adds depth without closing in the space.
6. Extend Tile to the Ceiling
Most builders tile showers to 6 feet and stop. Running tile all the way to the ceiling eliminates the visual "cap" that makes the shower feel like a box. It's also better from a waterproofing standpoint — steam rises, and a tiled ceiling is easier to clean than painted drywall.
7. Choose a Linear Drain
A linear drain along one wall allows the entire floor to slope in a single direction — no pyramid slope toward a center point drain. This lets you run large-format floor tile in one continuous piece without the complicated cuts required for a center-point drain, creating a cleaner, more modern look.
Layout Options for the Aurora 5×8
In a typical 5×8 bathroom, a tub occupies roughly 30×60 inches at one end. Removing it gives you several layout options:
- •Full-width shower (48–60×36): Use the full 5-foot width for a wide, walk-in shower with no door — just an open entry or a simple glass panel. Very spa-like.
- •Corner shower (36×36 or 36×48): Keeps more open floor space in the bathroom, making the overall room feel larger. Good if you have small children or pets to manage.
- •Alcove conversion (same footprint as old tub): Replace the tub with a shower in the same 30×60 footprint. Simple, lower cost, good results with the right tile design.
What to Budget in Aurora CO
A tub-to-shower conversion in the Aurora area typically runs $3,500–$8,000 for a basic alcove conversion with standard tile, and $8,000–$18,000 for a full custom walk-in with frameless glass, large-format tile, and a linear drain. Costs depend heavily on tile selection, glass enclosure style, and any plumbing modifications needed to relocate the drain.
Note: If yours is the only full bath in the house, Aurora building department and most lenders will flag the removal of a tub — consider your resale situation before going tub-free.
