Start with the basics: measure and visualize
Before you get excited about finishes or glass styles, take accurate measurements. Measure the width of the shower opening at three heights (top, middle, bottom) and the height from the finished floor to ceiling or the highest point you want the glass to reach. Record the smallest width measurement — that’s the one your door must fit.
Tip: use a metal tape measure and write down all three width numbers. If they don’t match, expect to pick an adjustable or custom door. Visualize how the door will swing or slide and how it fits with bathroom fixtures like towel bars or vanities.
Pick the right style for your space
There are three common styles that suit most bathrooms:
- Sliding (bypass) shower doors — great when you don’t have space for a swinging door. They’re ideal for tub-shower combos and narrow bathrooms.
- Hinged (pivot or swinging) doors — work well in larger showers where the door can open outward without colliding with fixtures.
- Frameless or semi-frameless doors — offer a clean, modern look. Frameless doors use thicker glass and minimal hardware; semi-frameless have a thin frame at the edge for extra support.
If you love a sleek modern look and have a roomy shower, a frameless shower door is a popular choice. If your space is tight or you’re on a budget, a sliding shower door often gives the best mix of value and convenience.
Understand glass thickness and safety
Glass thickness matters for both safety and appearance. Typical options:
- 1/4 inch (6 mm) — common for framed doors and lighter styles.
- 3/8 inch (10 mm) — a solid, middle option that balances weight and sturdiness.
- 1/2 inch (12 mm) — usual for true frameless doors for a premium look.
All shower glass should be tempered (safety glass). Tempered glass breaks into small, blunt pieces instead of sharp shards. When in doubt, choose thicker glass for frameless doors — it reduces flex and looks high-end.
Hardware, finishes, and maintenance
Hardware (hinges, tracks, handles) affects durability and style. Look for stainless steel or brass with corrosion-resistant finishes if your bathroom gets a lot of moisture. Common finishes include chrome, brushed nickel, and matte black.
For maintenance:
- Choose easy-clean glass coatings or apply a water-repellent seal to reduce soap scum.
- Avoid abrasive cleaners on coated glass or plated hardware.
- Periodically tighten screws and clean tracks on sliding doors to prevent binding.
Seals and water control — don’t skimp here
A good seal prevents leaks. Frameless doors often use slim rubber or vinyl seals along edges; sliding doors rely on sealed tracks. When shopping, check:
- If the door comes with seal strips and whether they’re easy to replace.
- If the threshold or bottom track is low-profile but designed to channel water back into the shower.
- Reviews or product specs that mention watertight or leak prevention.
If you plan to DIY, budget for extra seal strips and a tube of silicone caulk — they’re inexpensive and useful.
Tools and skills for DIY installation
Many shower doors are made for experienced DIYers. Typical tools you’ll need:
- Level (long one for accuracy)
- Drill with masonry and metal bits
- Screwdriver set and wrench
- Caulk gun and silicone sealant
- Tape measure and pencil
- Safety glasses and gloves
If the door is heavy (thick frameless glass), ask a friend to help during installation. Read the manufacturer’s instructions fully before starting. Take your time leveling the frame and tightening hardware incrementally — small adjustments prevent big problems.
Budgeting and choosing quality
A good rule: don’t chase the absolute cheapest door if you want long-term satisfaction. Quality components and better glass pay off in fewer leaks, less cleaning, and longer life. Compare:
- Warranty length (longer usually means better confidence from the maker)
- Included hardware quality (stainless tracks, solid hinges)
- Customer reviews about installation and longevity
For a mid-to-high income DIYer who values durability and style, a semi-frameless or framed high-quality sliding door often gives the best balance.
Final checking list before you buy
- Did you measure the narrowest width and desired height at three points?
- Does the door style fit your bathroom layout (swing vs. slide)?
- Is the glass tempered and at an appropriate thickness for the style?
- Is the hardware corrosion-resistant and backed by a warranty?
- Are seals and water-control features included or easy to replace?
- Do you have the tools and an extra pair of hands for installation?
Closing encouragement
Picking a shower door is a satisfying DIY project that can elevate your bathroom instantly. With careful measuring, a clear sense of the style you want, and attention to glass thickness and sealing, you’ll end up with a durable and attractive result. Take photos of your space, write down your measurements, and enjoy the process — you’ve got this!
