Project overview: Design, materials and prep work

The completed bathroom

We replaced all the fixtures, put down a new wood floor and tiled behind the sink, from floor to ceiling.

Here’s a surefire way to give your half bath a dramatic new look. Combine your choice of furniture with one of these basin-type DIY vessel sink ideas for a unique, custom-styled bath redo. This modern version of your great-grandma’s wash basin creates an eclectic style that looks great in contemporary or traditional settings.

The payoff: Transform the look of your half bath in three weekends.

• Add a spacious feel by replacing your vanity cabinet with a table.
• Combine the classic look of an old-fashioned vessel sink with the sleek style of a modern wall-mount faucet.
• Save wall patching work by using these easy-to-clean granite wall tiles.

The DIY vessel sink and wall-mount faucet cost more than standard off-the-shelf plumbing fixtures. But the combined cost of the table and plumbing fixtures we show is about the same as if you purchased a top-quality vanity cabinet, solid-surface vanity top and high-end faucet. And you’ll save at least half the cost of a professional bath remodel by doing the work yourself.

We’ll show you how to mount and connect the vessel sink and how to install the wall-mount faucet. And just in case your drain doesn’t line up or the plumbing vent gets in the way of the recessed faucet valve—don’t worry, we’ll show you how to relocate them too.

There are a few things you’ll want to check out before you start on elegant small bathrooms. If you live in a cold climate and your plumbing is on an outside wall, don’t use a wall-mount faucet because the valve and pipes could freeze. Use a standard-mount faucet instead. And second, look inside your vanity cabinet. If your water supply pipes come up from the bottom of the cabinet, you’ll have to reroute them into the wall. This could be a big job depending on how your house is constructed.

To complete our bathroom redo, we installed a new prefinished wood floor over the old vinyl and covered the wall behind the vanity with 12-in. square granite tiles. The granite cost us about $12 per sq. ft., but similar tile is available for about $4 per sq. ft. Plan on spending about $6 per sq. ft. for the wood floor. We spent $600 more on light fixtures and a new toilet. Here’s how you can save on a bathroom remodel.

Before you start this project, check with your building department. Most locales require a plumbing and electrical permit for this type of work. Then arrange for inspections before covering plumbing or electrical work with drywall.

Step 1: Remove old fixtures and open the wall

Photo 1: Remove the old vanity

Disconnect the trap and supply lines to the sink and pry off the vanity top. Locate and remove the nails or screws that hold the cabinet to the wall and remove the vanity cabinet.

Photo 2: Cut open the wall

Saw along the edge of the studs on both sides of the drain to at least 48 in. high. Tear off the drywall in this area.

Remove the old vanity cabinet (Photo 1). Then cut open your wall to install the faucet valve. There’s a good chance you’ll also have to relocate the drain, vent and light fixtures, so go ahead and cut a big hole (Photo 2). We removed a 4-ft. wide section of drywall. Turn off the power at the main circuit box before cutting and keep your cut shallow to avoid nicking electrical cables. If you tile the wall like we did, you won’t have any patching to do. Just screw a new piece of drywall to the new 2×2 cleats (Photo 14) and tile over it (Photo 15).

Step 2: Fit the sink and mark drain heights

Photo 3: Fit the vessel sink

Cut out the paper template supplied with your vessel sink and tape it to the center of the table. Drill a 1/2-in. starter hole inside the circle for the jigsaw blade. Then saw out the hole for the vessel sink with a jigsaw.

Photo 4: Set the drain

Roll a ball of plumber’s putty between your hands to form a putty ‘snake.’ Press the putty around the drain opening. Slide the top of the drain assembly through the drain hole and press it into the putty. Install the rubber washer, plastic washer and nut and tighten carefully until the drain is secure and flush with the bowl.

Photo 5: Set the sink

Squeeze a pencil-width bead of silicone caulk (caulk is usually provided by the sink manufacturer) around the sink cutout and lower the sink into the hole. If your drain has a fancy pop-up lever like ours, face it to the front.

Photo 6: Mark the drain height

Center the table in its final location. Hold the P-trap assembly level and as high as possible on the tailpiece and mark the center on the wall.

Photo 7: Mark the faucet spout height

Hold the faucet spout above the sink and mark its center on the wall. Ask your plumbing inspector for the minimum height above the rim. Here, the spout outlet is about 3 in. above the rim of the vessel.

Marking in place is better than math and measuring. Rather than trying to calculate the height of the drain and faucet, it’s easier and safer to assemble your table and sink (Photos 3–5) and mark the center of the drain and faucet heights directly (Photos 6 and 7). Before you cut the hole in your table, make sure the back edge of the bowl will be a few inches from the wall. Also measure from the front of the table to make sure the front of the hole will clear the table apron below. Next mark the center of the table on the floor. Plumb up from this mark with a level to locate the center of the drain and faucet spout (Photo 5, 7 and 8).

Step 3: Shift plastic drain lines

Photo 8: Cut off old pipes

Turn off the water at the main shutoff valve and cut the water supply lines with a tubing cutter or hacksaw. Saw through the drain about a foot from the floor. Saw through the horizontal section of the vent pipe. Remove the sawed-out section of drain and vent.

Photo 9: Reframe as needed

Cut the stud and reframe the opening as shown if necessary to accommodate the valve (Photo 11). Drill a 2-1/8-in. hole through the stud centered on the new drain height and another hole below that to reconnect the drain and vent.

Photo 10: Assemble the new drain line

Cut plastic pipe and reroute the drain and vent as shown. Prime the pipe ends and the inside of fittings. Then spread PVC adhesive on the primed surfaces and quickly assemble each joint, twisting the pipe about a quarter turn as you push it into the fitting.

The faucet valve mounts in the space between the wall studs. With the faucet and drain centers marked, it will be obvious whether you’ll have to move the drain and water supply lines to make everything fit. You may also have to remove a portion of one wall stud. Photo 9 shows how to reframe the opening. Photo 10 shows one method of relocating a drain and vent using 1-1/2 in. plastic PVC pipe and fittings. Your plumbing may not look like this. If you have steel rather than plastic pipe, use a reciprocating saw with a metal-cutting blade to cut the pipes. Run the new pipes in PVC and connect to the steel pipe with transition couplings. Here are a few other rules for reworking your drain and vent plumbing:

• Use clamping neoprene transition couplings to connect steel pipe to plastic pipe or to connect black (ABS) pipe to white (PVC) pipe.
• Continue the vent pipe vertically or at a 45-degree angle to at least 6 in. above the top rim of the vessel sink before running it horizontally.
• Use a long sweep 90-degree elbow where the drain turns from vertical to horizontal (Photo 10).

Step 4: Mount the new faucet valve

Photo 11: Mount the faucet valve

Follow the instructions provided with the valve for locating the blocking and attaching the valve.

Photo 12: Run copper supply lines

Connect the valve to the supply lines with 5/8-in. outside diameter soft copper. Estimate the length needed and allow an extra 6 in. Slide a bending spring over the copper to prevent kinking. Bend the copper to fit. Hold it in place and mark the ends.

Photo 13: Solder the copper

Cut, clean, flux and solder the copper tubes and fittings to connect the hot and cold supply lines to the new valve. Test the valve according to the instructions provided before covering the wall with drywall and tile.

The instructions included with our valve specified fastening the valve to two 2×4 blocks spaced 5-5/8 in. apart. It’s critical that you mount the valve the correct distance back from the finished wall surface. Otherwise your faucet trim and spout may not fit properly. Check the instructions, since this distance will vary by faucet brand. To make sure of this dimension, we completely assembled the valve and trim and measured the distance from the mounting bracket to the back of the handle and spout trim. If you’re tiling the wall, add the tile thickness to your calculation.

Complete the plumbing work by connecting the hot and cold water lines to the valve (Photos 12 and 13). We used copper pipe, but in areas with corrosive water, consider CPVC. Rather than using rigid copper, buy a length of 5/8-in. outside diameter (O.D.) soft copper (Type L) and bend it to fit. You’ll save time and potential leaks by drastically reducing the number of fittings needed. Buy a bending spring and slip it over the copper before you bend it to avoid kinking the copper (Photo 12). When soldering, protect walls and pipes with a heat shield (Photo 13). When finished, turn on the water and test the valve according to the instructions included.

Finally, add nail-plates wherever supply pipes or drains pass within 1-1/2 in. of the face of the framing. This prevents accidental punctures from nails and screws.

Step 5: Relocate lights while the wall is open

Photo 14: Relocate light fixtures

Relocate the light fixture boxes if necessary. Turn off the power at the main circuit box and test the wires to be sure it’s off. Carefully pry the boxes loose and remove the staples that hold the cables in place. Add blocking or slide the box on its strap to relocate it. Reattach the boxes and staple the cables within 8 in. of the box.

If you add tile to the wall, make sure the face of the electrical box is no more than 1/4 in. behind the surface of the tile. At the same time, adjust the location of the boxes if necessary. Make sure they’re level with each other and are located an equal distance from the centerline of the table. Purchase the mirror and light fixtures ahead of time and hang them temporarily to create a full-scale mock-up. From this, measure the height and the distance between the light fixtures and relocate the existing boxes to these positions.

Now’s a good time to upgrade your bath wiring, especially if your house is more than eight years old. Ask your local electrical inspector what’s required. If your bathroom has aluminum wire, or you’re unsure whether there is a proper ground for your light fixtures, call an electrician.

Caution: Before you do any electrical work, turn off the power at the main circuit panel. Test the wires with a voltage tester to make sure they’re off. Also, aluminum wiring requires special handling. If you have aluminum wiring, call in a licensed pro who’s certified to work with it. This wiring is dull gray, not the dull orange that’s characteristic of copper.

Step 6: Tile the wall

Photo 15: Level the first tile row

Level the first course of tile with small plastic shims, available at tile retailers. Mark a line with a 4-ft. level to indicate the top of the first row of tile. Draw vertical plumb lines at the outside edges. We extended the tile 1 in. beyond the table on each side.

Screw cleats alongside the two outsidestuds as nailers for the drywall.Cut drywall to fit the opening andscrew it to the studs and cleats. Nowyou’re ready to set the wall tile.Start by planning the layout. Centerthe tiles side to side to maximize thesize of the cut tiles along the edges(you may not have to cut any tile atall). We started with a full 12-in. tileat the floor and cut the border tilesto 8 in. wide. Draw layout lines and set the tiles in premixed latex tileadhesive (Photo 15). Use spacersbetween tiles to create a space forgrout, or set the tiles tight togetheras we’ve done. Practice by dry-layingthe tiles on the floor first to seehow well they fit together.

The flamed granite tile we used isvery hard. You’ll need to rent a wet-cuttingtile saw for the straight cuts. Holes for the faucetshave to be cut precisely. We used a2-in. diameter abrasive-coated tile-cuttinghole saw (available at home centersor tile retailers). It took aboutfive minutes to drill each hole! Mosttile shops will cut these holes foryou for a minimal charge. Make acardboard template to ensure exact
hole location before cutting the tile.

Step 7: Make the final plumbing connections

Photo 16: Connect the drain

Cut the tailpiece to extend about 1-1/2 in. into the trap and thread it into the drain assembly. Use a hacksaw with a fine-tooth blade to cut the tubing. Cut the trap arm if necessary to extend about 2 in. into the wall when it’s aligned with the trap. Slide the trap up onto the tailpiece and connect it to the trap arm with the rubber slip joint washers and large slip joint nuts provided. Hand-tighten them. Then tighten them an additional quarter turn with a large slip joint pliers.

Photo 17: Assemble the faucet

Assemble the spout, faucet handle and rings to the faucet valve according to manufacturer instructions.

Screw the table to the wall and connect the trap to the sink drain (Photo 16). Then install the faucet trim (Photo 17) to finish the plumbing part of your job. We also installed a new toilet and light fixtures. Paint the walls and hang shelves, a towel bar and a paper dispenser, and your bath redo is complete.
