What Tools and Materials Do You Need?
Before turning off your water supply, gather these essentials:
Tools:
Adjustable wrench
Pipe cutter or hacksaw
Teflon tape (plumber’s tape)
Basin wrench
Level
Tape measure
Screwdrivers (Phillips and flathead)
Silicone caulk and caulking gun
Materials:
Glacier Bay shower and tub faucet kit (e.g., model #86657W-AMZ)
Supply lines (usually included)
Drain assembly (check compatibility with your tub)
⚠️ Safety First: Turn off the main water supply and open faucets to relieve pressure before beginning any plumbing work.
Step-by-Step: How to Plumb a Shower and Tub Using Glacier Bay
Step 1: Remove Old Fixtures (If Applicable)
Shut off water supply.
Disconnect supply lines and remove old valve trim, spout, and handles.
Clean the wall surface and inspect for leaks or corrosion in existing pipes.
Step 2: Install the Rough-In Valve
Most Glacier Bay tub/shower combos use a single-handle pressure-balancing valve. This valve controls both temperature and flow while preventing scalding—a feature required by modern plumbing codes.
Slide the valve body into the wall opening (typically between studs).
Secure it with mounting screws.
Solder or connect to hot and cold water lines using copper or PEX piping (follow manufacturer specs).
Cap test ports and pressure-test the system for leaks (run water for 10–15 minutes).
📏 Precision Matters: Ensure the valve is level and centered. Misalignment can cause trim pieces to fit poorly.
Step 3: Install the Tub Spout
Glacier Bay offers two common spout types: slip-on and threaded.
Slip-on: Slide over a ½” copper pipe extending from the wall. Tighten set screw underneath.
Threaded: Screw onto a male iron pipe (MIP) adapter. Wrap threads with Teflon tape (3–4 wraps clockwise).
✅ Check Flow: The spout should direct water straight into the tub without splashing. Adjust pipe length if needed.
Step 4: Mount the Shower Arm and Head
Thread the shower arm into the top outlet of the valve.
Use Teflon tape on threads to prevent leaks.
Attach the showerhead (most Glacier Bay models use a standard ½” connection).
Hand-tighten, then give a quarter-turn with a wrench—do not overtighten.
Step 5: Install Trim and Handle
Slide escutcheon plates over valve stems.
Attach handle(s) using included screws.
Test operation: turning left = hot, right = cold; pulling = shower mode.
🔧 Note: Glacier Bay’s diverter is usually built into the tub spout. When you pull up on the spout, water redirects to the showerhead.
Step 6: Connect Supply Lines & Test for Leaks
Reconnect hot and cold supply lines to shut-off valves.
Slowly turn water back on.
Check all connections for drips. Tighten slightly if needed—but remember, over-tightening cracks fittings.
Glacier Bay stands out for budget-conscious DIYers who don’t want to sacrifice quality. Their universal valve systems also simplify replacements down the line.
FAQ Section
Q1: Can I install a Glacier Bay shower and tub myself?
A: Yes! Glacier Bay designs its kits for DIY installation. If you’re comfortable with basic plumbing (shutting off water, using wrenches, and reading instructions), you can do it in a weekend. However, if your walls are open or you’re rerouting pipes, consider hiring a licensed plumber.
Q2: Do I need a permit to replace my tub and shower fixtures?
A: In most U.S. cities, replacing fixtures without altering plumbing lines does not require a permit. But if you’re moving valves, adding new lines, or changing drainage, a permit is usually required. Always check with your local building authority.
Q3: Why is my Glacier Bay shower not switching to tub mode?
A: This usually means the diverter inside the tub spout is stuck or clogged. Try cleaning the spout with vinegar or replacing it. Glacier Bay spouts are inexpensive and easy to swap.
Q4: How long does installation take?
A: For a straightforward replacement (same valve location, no wall repairs), expect 4–6 hours. First-timers may take a full day. Plan accordingly!
Q5: Are Glacier Bay fixtures compatible with older plumbing?
A: Most Glacier Bay trim kits fit standard U.S. rough-in valves (like those from Price Pfister or older Moen). However, always verify compatibility using Glacier Bay’s online tool or by measuring your existing valve stem.
Q6: Can I use PEX tubing with Glacier Bay valves?
A: Yes—many Glacier Bay rough-in valves support PEX, copper, or CPVC. Just ensure you use the correct adapters and follow local code requirements for pipe type.
