Small Bathroom Expansion: Adding a Shower to a Powder Room
Complete transformation from powder room to full bathroom with shower - passed inspection on first attempt
Project Overview
A complete bathroom transformation that converted a compact powder room into a fully functional bathroom with shower. This townhouse renovation required concrete cutting, new plumbing installation, and careful space planning to maximize functionality in a limited footprint.
The Challenge
The homeowner approached us with a clear vision: transform their first-floor powder room (toilet and vanity only) into a complete bathroom by adding a shower. This wasn't a simple cosmetic update—it required significant structural and plumbing work.
Key Obstacles:
- Limited space requiring precise layout planning
- First-floor location with concrete slab flooring
- Need to access existing plumbing lines
- Required city inspection approval
- Integration of new plumbing without disrupting existing systems
Our Solution
Phase 1: Plumbing & Infrastructure
Concrete Cutting & Access
Working on a first-floor concrete slab, we carefully cut through the concrete to access the existing plumbing infrastructure. This precision work allowed us to tie into the toilet's waste line for the new shower drain without compromising the building's structural integrity. All work followed Denver building code requirements.
Water Supply Installation
We ran hot and cold water lines from the boiler room located directly behind the adjacent wall. This proximity made installation efficient and minimized disruption to other areas of the home.
Shower Drain Installation
Created a new drain line connecting to the existing toilet waste system, ensuring proper slope and drainage capacity according to TCNA (Tile Council of North America) standards and local plumbing codes.
Phase 2: Inspection & Approval
Passed on First Attempt
All plumbing work was submitted for city inspection. Our installation passed inspection on the first attempt, allowing us to proceed immediately to the finishing phases. The inspector commended the quality of our plumbing work and attention to code requirements.
This successful inspection is a testament to our team's expertise and commitment to quality workmanship. We handle all permit applications and ensure every aspect of your bathroom renovation meets or exceeds local code standards.
Phase 3: Tile & Finishing Work

Materials Used
All materials were sourced from trusted suppliers and selected for durability in Colorado's climate. We use only products that meet or exceed industry standards set by organizations like the Tile Council of North America and approved by the National Kitchen & Bath Association (NKBA).
The Best Compliment: A Referral
Two months after completing this project, we received a call from the homeowner's neighbors—also townhouse residents and close friends. After visiting and seeing the transformation, they immediately wanted the same renovation for their own bathroom.
This neighbor-to-neighbor referral resulted in our second identical bathroom expansion project, proving that quality work speaks for itself. There's no better endorsement than a customer who's so satisfied they recommend us to their friends and neighbors.
Results
The transformation successfully converted an underutilized powder room into a fully functional bathroom, adding significant value and convenience to the home.
The modern black-and-white design aesthetic creates a clean, spa-like atmosphere while maximizing every inch of available space. The homeowner gained a complete bathroom without the need for a costly addition or major structural changes.
Benefits Achieved:
- Fully functional bathroom with shower
- Modern, timeless design aesthetic
- Passed inspection on first attempt
- Waterproof, durable materials
- Increased home value
- Generated neighbor referral
Frequently Asked Questions
Common questions about powder room to bathroom conversions
Can you really add a shower to an existing powder room?
Yes! With proper planning and professional execution, many powder rooms can accommodate a compact shower. We assess your space, existing plumbing, and structural considerations to determine feasibility during your consultation.
What's involved in cutting through a concrete slab for plumbing?
We use specialized concrete cutting equipment to precisely access the area needed for new drain lines. The concrete is then properly patched and sealed. All work is done to code and inspected by the city to ensure structural integrity and safety.
Do bathroom plumbing additions require inspection?
Yes, in most municipalities including Denver and Wheat Ridge, new plumbing work requires permits and inspection. We handle all permit applications and ensure work meets local code requirements. Our installation passed inspection on the first attempt.
How long does a bathroom expansion project take?
This project took approximately 2 weeks from demolition to completion. Timeline includes plumbing work, inspection wait time, and all finishing work. We'll provide a detailed schedule during your consultation.
What is LVT flooring and why use it in bathrooms?
Luxury Vinyl Tile (LVT) is a waterproof, durable flooring option that looks like wood or stone but performs better in wet environments. It's ideal for bathrooms due to water resistance, easy maintenance, and comfort underfoot.
Can you work on townhouses or condos?
Absolutely. We're experienced with multi-family dwelling regulations and work closely with HOAs and building management when required. We handle all necessary approvals and ensure work meets building-specific requirements.
What if my bathroom is even smaller?
We specialize in maximizing small spaces. During consultation, we'll measure your bathroom and provide options for shower sizes and configurations that will work. Even very compact spaces can often accommodate a shower with the right planning.
