Many homeowners in Plano, Frisco, and North Dallas ask us:
“Can I turn my half bath into a full bathroom with a shower?”
The short answer: Yes, you can, but it requires the right space, plumbing, and planning. Adding a shower to your powder room can improve functionality, increase your home’s value, and make daily living easier. But not every half bath is a good candidate for a shower conversion.
In this blog post, we’ll cover everything you need to know about adding a shower to your half bath, from space requirements to design solutions and cost considerations.
Why Bathroom Size Matters
Half baths, or powder rooms, are typically 18–24 sq. ft., just enough for a toilet and sink. Adding a shower requires expanding that footprint.
- Minimum shower size by code: 30” x 30”
- Comfortable shower size: 36” x 36” or larger
- Recommended total half bath + shower footprint: at least 5’ x 7’ (35 sq. ft.)
If your current powder room is around 3’ x 5’, it’s not practical to squeeze in a shower. You’ll need to borrow space from an adjacent closet, hallway, or utility area.
Key Considerations for Adding a Shower
Turning a half bath into a full bath isn’t just about squeezing in a shower. You’ll need to think about:
1. Layout & Doors
Traditional swing doors take up precious floor space. Instead, consider:
- Pocket doors that slide into the wall
- Barn doors that slide along the exterior
Both free up room inside the bathroom for a better layout.
2. Shower Type
Smaller spaces benefit from:
- Corner showers with curved or angled bases
- Glass enclosures that make the room feel larger
- Walk-in showers for a modern, open look
3. Plumbing Upgrades
Showers require:
- A 2-inch drain line (vs. 1.5-inch for sinks)
- Possible upgrades to older pipes and venting
- Water pressure checks to ensure proper flow
4. Ventilation
Moisture is the enemy of small bathrooms. Without a strong exhaust fan, mold and mildew will develop quickly. We recommend installing:
- High-capacity exhaust fans vented outside
- Humidity sensors that auto-activate the fan
5. Lighting & Storage
Since small bathrooms can feel cramped, smart design is essential:
- Recessed lighting for brightness
- Niches built into the shower walls for toiletries
- Floating vanities that free up floor space
Pro Tip: Borrowing Space
If your half bath shares a wall with a closet, hallway, or laundry area, you may be able to “borrow” a few feet to reach the 5’ x 7’ minimum footprint. This is often the most cost-effective way to add a shower without major structural changes.
Why Adding a Shower Is Worth It
Adding a shower transforms your half bath into a three-quarter bath (¾ bath), which can significantly improve both your lifestyle and your home’s resale appeal.
- Functionality: Guests, kids, and multigenerational households all benefit from the extra shower.
- Value: In today’s Plano, Frisco, and North Dallas real estate market, buyers love having an additional bathroom option.
- Design: With modern fixtures, glass enclosures, and quality finishes, even a small bath can look luxurious.
