Planning and Design
Careful planning lays the foundation for a functional and cost-effective outdoor shower. The choices you make during this stage will directly impact installation expenses, how often you’ll use the shower, and whether it becomes a practical addition or an underused feature.
Choosing the Right Location
Picking the right spot is crucial. Position your shower near existing plumbing to keep installation costs down. Extending water lines typically requires trenching, extra materials, and additional labor, which can quickly add up.
Privacy is another key consideration. In urban settings, you’ll likely need taller enclosures or placement behind your house to block sightlines. Suburban homeowners in areas like Howard County or Carroll County often have more flexibility, but it’s still smart to factor in views from neighboring windows.
Accessibility matters, too. Place the shower near high-traffic zones like the pool or back door. A shower tucked into a remote corner might go unused, no matter how well-designed it is.
Don’t forget about local regulations. Zoning and setback rules may limit where you can install your shower. For example, Baltimore County requires permits for outdoor showers and enforces specific rules about drainage and distances from property lines. Always check your county’s requirements before starting.
Maryland’s clay-heavy soil presents another challenge. Proper drainage is essential to prevent water from pooling, which could lead to code violations or long-term issues. Avoid low spots and plan for robust drainage solutions to handle the region’s weather.
Once you’ve chosen a location, shift your focus to a design that can handle Maryland’s unique climate.
Design Options and Materials
When selecting materials, prioritize durability to withstand Maryland’s humid summers, freezing winters, and frequent rainfall. Your material choices will directly affect the shower’s lifespan and performance.
Here’s a breakdown of design types and their pros and cons:
| Design Type | Privacy Level | Optimal Materials | Pros | Cons |
|---|---|---|---|---|
| Open-Air | Low | Stone, composite decking | Easy to install, natural feel | Limited privacy, exposed to weather |
| Partially Enclosed | Medium | Cedar, lattice, stainless steel | Customizable, some weather protection | Moderate cost, partial weather exposure |
| Fully Enclosed | High | Treated wood, vinyl, stone | Maximum privacy, year-round use | Higher cost, more complex installation |
For Maryland’s climate, materials like cedar and teak are excellent choices. They naturally resist rot, insects, and the region’s temperature swings without warping or cracking. Stainless steel is ideal for fixtures and hardware because it resists rust in humid conditions and stands up to chlorinated pool water. If you’re in a coastal area, marine-grade stainless steel offers even more protection.
Flooring is another critical factor. Opt for slip-resistant materials like textured stone, concrete pavers, or composite decking. Avoid smooth tiles or untreated wood, as they can become dangerously slippery when wet and may not hold up well in Maryland’s climate. Pressure-treated lumber is another option, but it requires regular sealing to maintain its durability and appearance.
Water efficiency is also regulated in Maryland. Since January 1, 2020, all showerheads must have a maximum flow rate of 2.0 gallons per minute at 80 PSI [1][2]. This not only helps conserve water but also reduces water heating costs while maintaining sufficient pressure for outdoor use.
Think about seasonal adaptability when designing your shower. Partially or fully enclosed structures can extend its usability into Maryland’s cooler months. Adding a roof or partial walls can provide extra protection from the elements, making the shower more versatile.
For a polished look, consider hiring professionals to integrate your outdoor shower into your overall landscape. Companies like Pro Landscapes MD specialize in creating cohesive designs that include proper grading, drainage, and seamless blending with existing features like patios or walkways. This approach can transform your shower from a standalone feature into a natural extension of your outdoor space.
Local Regulations and Permits in Maryland
Setting up an outdoor shower in Maryland means navigating a maze of plumbing codes, permits, and drainage regulations. Getting familiar with these rules early can save you from unnecessary delays or fines. Plus, these requirements tie closely to the design and planning steps you’ve already considered.
Maryland Plumbing Codes
Maryland adheres to the International Plumbing Code (IPC) but includes state-specific amendments, collectively known as the Maryland Plumbing Code. These rules govern all plumbing installations in the state [3]. Every fixture must connect to an approved water supply and drainage system unless an alternative system has been officially approved [3].
There’s no room for shortcuts when it comes to materials. Only components meeting standards set by ASME, ASTM, CSA, and NSF are allowed, and they must be installed according to the manufacturer’s guidelines [3][4].
"Plumbing shall be installed with due regard to preservation of the strength of structural members and prevention of damage to walls and other surfaces through fixture usage." – MD Board of Plumbing, Plumbing Code 2018 [3]
The code also requires water, soil, and waste pipes to be protected from freezing, corrosion, and physical damage [3]. Fixtures must have smooth, non-porous surfaces for easy cleaning, and all joints where fixtures meet walls or floors must be sealed properly to avoid water damage [4].
Permit Requirements
With the plumbing standards in mind, the next step is securing the necessary permits. Plumbing work in Maryland counties always requires permits, though the process and rules might differ depending on your location. For instance, in Carroll County, homeowners can apply for plumbing permits themselves if they live on the property [5]. Other counties may have more restrictive policies.
You’ll need to submit detailed plans showing your shower’s location, plumbing setup, and drainage design for review. This ensures your project complies with zoning laws, building codes, and other regulations. Skipping this step could lead to fines and complications when selling your property [5]. If your home is within a city’s boundaries, check with both city and county officials, as additional rules might apply.
Inspections are part of the process too. An initial inspection is typically conducted after the rough plumbing is installed but before it’s covered up. A final inspection follows once everything is complete to confirm the installation meets all codes [3].
Drainage Compliance
Maryland’s drainage rules aim to prevent water buildup. For example, in Prince George’s County, properties must be graded to avoid stagnant water around structures [6]. Your outdoor shower’s drainage system should connect to a public sewer or an approved private septic system [6].
If drainage seems tricky, it’s worth consulting a professional. Companies like Pro Landscapes MD specialize in creating drainage systems that meet both functional needs and regulatory standards. Proper drainage design is a key step before moving on to the installation phase, which will be covered in the next section.
Step-by-Step Installation Process
With permits in hand and drainage plans approved, it’s time to dive into building your outdoor shower. The process demands careful attention to detail, especially considering Maryland’s climate and local building codes.
Site Preparation and Foundation
Start by marking the shower area and digging down 8–10 inches to create a stable foundation that promotes proper drainage [7]. Clear away any obstacles in the area.
Compact the soil using a hand tamp to prevent future settling [7]. Check if additional drainage measures are necessary to avoid water pooling under the foundation [7].
Next, frame the shower pan using 2″×6″ lumber and add rebar for reinforcement [7]. Be sure to create a drainage slope of at least ¼ inch per foot toward the drain. Using a laser level can help ensure accuracy [7].
Pour the foundation with Rapid Set 24/6 Concrete Mix, and include a 2‑inch PVC drain pipe for water runoff [7]. Once poured, smooth the surface with a float and edging trowel. Aim for a finish that’s smooth enough for tiling but textured enough to prevent slipping [7].
With the foundation ready, the next step is to install the plumbing and fixtures.
Plumbing and Fixture Installation
Follow Maryland plumbing codes closely when installing fixtures. Test all connections for leaks using water or air pressure before sealing up the pipes [3][4]. Maryland regulations require fixtures to have smooth, non-porous surfaces for easy cleaning and maintenance [4]. Additionally, install backflow prevention devices as required by state guidelines when running water supply lines [3].
Make sure all fixtures comply with Maryland standards. If you’re adding extra features like a hand-held sprayer, ensure the total water flow stays within legal limits.
When mounting fixtures, keep them level and aligned with the surrounding walls [4]. For tiled finishes, use thin-set mortar and seal all joints around fixtures and between walls or floors to prevent water damage [4][7]. To protect against Maryland’s freezing winters, insulate exposed pipes and install a shut-off valve inside your home to prevent burst pipes.
Once you’ve tested the plumbing for leaks and confirmed everything is working, move on to enclosing the shower and adding the final touches.
Enclosure and Finishing Touches
Complete your outdoor shower with privacy screens or walls. Select materials designed to endure Maryland’s humid summers and cold winters. Popular choices include cedar, pressure-treated lumber, composite materials, or masonry – just make sure there’s proper drainage behind the structure.
Apply weatherproof finishes to protect the materials. For tiled areas, grout and caulk all corners and joints evenly [7]. Secure hardware and test water flow to ensure everything functions as intended.
To improve drainage around the shower, consider placing landscape fabric and stone around the area. This helps manage standing water and mud during Maryland’s frequent rainy seasons [7]. Pro Landscapes MD often incorporates these features into outdoor shower projects, blending functionality with visual appeal for homes across central Maryland.
Finally, document your work with photos for future reference. Keep all permits and manufacturer warranties handy in case of inspections or repairs down the line.

Maintenance and Seasonal Care
Taking care of your outdoor shower after installation is key to preserving its functionality and protecting your investment. Maryland’s changing climate makes regular upkeep even more important to ensure your shower remains in top condition and compliant with local codes.
Cleaning and Routine Maintenance
Keeping your outdoor shower clean is crucial, especially during Maryland’s humid summers when bacteria, mold, and algae can thrive.
- Weekly upkeep: Rinse the shower with fresh water to clear away dirt and salt. Then, dry all surfaces with a microfiber cloth to avoid water spots and mineral deposits.
- Monthly care: Take a closer look at caulk and grout for any gaps or cracks that could lead to leaks. Flush the drain with a mix of baking soda and vinegar to prevent buildup and maintain proper drainage.
- Tackling stains and rust: Use a stainless-steel cleaner or a baking soda paste for rust spots. For mold or mildew, natural options like white vinegar or hydrogen peroxide work well without relying on harsh chemicals. Since grout is especially prone to mold, reapplying a grout sealer every six months helps keep it watertight.
Here’s a quick reference table for your maintenance routine:
| Maintenance Task | Frequency | Purpose |
|---|---|---|
| Rinse with fresh water and dry | Weekly | Removes debris and prevents water spots |
| Inspect caulk and grout | Monthly | Identifies gaps to prevent leaks |
| Flush drain with baking soda & vinegar | Monthly | Reduces buildup and ensures proper drainage |
| Reapply grout sealer | Every 6 months | Maintains watertight joints |
As winter approaches, it’s time to shift gears and prepare your outdoor shower for colder weather.
Winterization
Maryland’s freezing temperatures, typically from late October through early March, can wreak havoc on outdoor plumbing. Winterizing your shower before the first frost is essential to avoid costly freeze damage.
- Shut off the water supply: Open all valves and use an air compressor to clear out any trapped water. Even a small amount of leftover water can freeze and cause damage.
- Remove and store fixtures: Detach removable parts like shower heads and hose bibs, and store them in a heated space to prevent cracking from freeze-thaw cycles.
- Protect exposed pipes: Insulate pipes with foam covers or heat tape, especially those running along exterior walls or through unheated areas. For extra precaution, pour a small amount of pipe-safe antifreeze into the shower drains.
- Cover the structure: Use a waterproof cover or heavy-duty tarp to shield the shower from snow, ice, and storms. Secure the covering tightly to prevent wind damage, but allow for some airflow to reduce condensation.
If your shower system is more complex or integrated with landscaping features, Pro Landscapes MD recommends professional winterization services. Their familiarity with central Maryland’s climate can help ensure your shower stays protected during even the harshest winters.
When spring rolls around, reverse the winterization process step by step. Carefully inspect all connections, seals, and caulking for any winter-related damage before turning the water back on. This gradual approach helps ensure everything is ready for another season of use.
Conclusion
Adding an outdoor shower to your Maryland backyard can transform your space into a functional and refreshing retreat, no matter the season. As architect Howard Backen perfectly puts it:
"Invigorating when it’s cold, interesting when it’s rainy, and incredibly refreshing when it’s sunny and hot" [8].
