Get a Polished, Built-In Look with Shower Surround Trim
Upgrading a basic shower to create a high-end, built-in look is easier than you think. By adding trim molding around your shower walls and enclosure, you can give your bathroom a polished, finished appearance without a complete remodel.
Shower surround trim, also called wall trim or edging, frames the shower area for a seamless, built-in aesthetic. Continue reading to learn all about shower trim materials, installation tips, and design ideas to elevate your bath.
Materials for Shower Surround Trim
Trim molding comes in a variety of materials to suit any design. Here are some of the most common options:
- PVC: Polyvinyl chloride plastic is waterproof, low-maintenance, and affordable. It's easy for DIY installation and comes in many colors.
- Composites: Engineered wood and resin materials resist moisture and mimic finishes like marble or granite.
- Metals: Sleek aluminum, stainless steel, or brass trims add a touch of contemporary style.
Consider factors like bathroom humidity, cleaning requirements, and desired aesthetics when selecting your materials. Metal trims offer durability and a modern look, while PVC provides budget-friendly waterproofing.
PVC Trim
Polyvinyl chloride (PVC) is a lightweight and durable plastic perfect for high-moisture areas. PVC trim resists scratches, stains, and mold and is easy to clean.
With bendable PVC boards and adhesive, DIYers can achieve professional results. Installation only requires basic tools like a saw, drill, and caulk gun. Combining simplicity and customization, PVC is ideal for beginners looking to increase water protection and add decorative trim.
Composite Trim
Composite shower trim contains materials like wood, plastic, and stone dust fused into solid boards. Composites blend natural stone and wood looks with durability.
Made to withstand humidity, composite trims are mold, mildew, and moisture-resistant. Though more difficult to cut than vinyl, composites better mimic high-end finishes.
Pair composite trim with matching shower walls for a cohesive built-in style. With the right skills, composite molding offers customization and aesthetic appeal.
Tools and Materials
Installing shower trim molding is an easy DIY project. Be sure you have these essential tools and materials on hand:
- Trim molding lengths
- Miter saw or hacksaw
- Tape measure
- Pencil
- Caulk gun
- Silicone caulk
- Adhesive or nails
- Sandpaper
Choosing quality silicone caulk is key for waterproofing. A miter saw makes quick work of angled cuts, though a hacksaw can also be used. Have extra trim available for mistakes!
Preparing the Shower Walls
Proper prep ensures trim molding adheres correctly. Follow these steps:
- Clean surfaces with a nonabrasive cleaner and rinse.
- Remove old caulk or adhesive with a caulk removing tool.
- Fill any holes or cracks with silicone sealant.
- Smooth any bumps or texture with sandpaper.
All surfaces should be dry, debris-free, and ready for install. Check for existing mildew and treat prior to installing trim.
Measuring and Cutting
Carefully measuring and cutting the molding prevents gaps or mismatched seams.
- Measure the height of each wall and length of top and sides.
- Transfer measurements and cut trim pieces to size.
- Make 45 degree mitered cuts for a professional finish.
- Use a miter saw or hacksaw with miter box for accuracy.
Take your time to make clean cuts. Sand any rough edges smooth for flawless corners. Cut several small test pieces to perfect technique before cutting longer trim lengths.
Installing Trim Molding
Follow these tips for a seamless installation:
- Apply adhesive or nails every 8-12 inches.
- Ensure trim fits tightly against shower walls.
- Fill gaps with silicone caulk for waterproofing.
- Use quarter round trim to finish vertical corners.
- Practice first on scrap materials to get the hang of it.
Take care to keep trim level and pressed firmly in place. Nails or construction adhesive provide secure attachment to surround walls.
Sealing with Silicone Caulk
Waterproofing the trim molding finish requires a quality silicone caulk. Follow these caulking tips:
- Run a smooth, consistent bead along all trim edges and seams.
- Use a wet finger or caulking tool to spread the caulk smoothly.
- Make sure caulk makes full contact with the shower walls.
- Let cure 24 hours before exposing to water.
Take time filling any gaps or corners fully with caulk. Proper sealing prevents leaks and moisture damage.
Design Options
The design choices for shower trim molding are endless. Consider options like:
- Colors - glossy white, chrome, bronze, black
- Textures - smooth, matte, brushed
- Patterns - etched designs, accent inlays
- Materials - aluminum, moisture-proof composites
Complement your faucets and showerhead finishes with similar trim molding metals and colors. Or make the trim a bold accent shade against neutral tile.
Maintaining Molding
Keep your shower trim looking fresh with simple care:
- Clean monthly with mild detergent and water.
- Immediately dry any water exposure.
- Check caulk for cracks and re-apply as needed.
- Avoid abrasive cleaners that can dull the finish.
Using mold-resistant materials can further extend the life of trim molding in humid environments. Proper maintenance keeps trim looking like new.
Achieving a Built-In Look
Details like extending wall tile into the shower and cohesive caulk colors further enhance the built-in style. Try these tips:
- Use matching grout color in shower and on surrounding walls.
- Continue wall tile patterns seamlessly into the surround.
- Install floor-to-ceiling trim molding for an alcove effect.
- Add quarter round trim to finish vertical edges.
A frameless glass enclosure, shampoo niche, and recessed lighting also blend the shower into the bath design.
Enhance Functionality
Built-in showers not only look great, but also improve usability through smart additions like:
- Corner shelves, shampoo nooks, and storage
- Towel rods, hooks, and grab bars
- Recessed or waterproof lighting
- Doors that fold back or slide seamlessly
- Built-in or wall-mounted benches or seats
With style and function combined, your new built-in shower will be a luxurious highlight of your bath.
Transforming your existing shower into a high-end built-in doesn't have to be difficult or expensive. The simple addition of trim molding frames the space for a polished, upscale aesthetic.
