Bathroom Remodels

Bathroom remodel plumbing, from rough-in to jewelry.

Every beautiful bathroom is decided behind the tile. Panda Plumbing carries the plumbing side of bathroom remodels across the east Portland metro: drains relocated with correct slope and venting, curbless pans engineered to actually drain, in-wall carriers set solid for floating fixtures, and the trim you fell in love with installed exactly as the designer drew it.

Behind the Tile

The plumbing decides what your bathroom can be.

Tile, stone, and brass get all the attention, but a bathroom floor plan is really a plumbing document. Move the shower to the far wall and its drain has to travel too, re-sloped and re-vented from the new location. Float the vanity and the supplies and trap that used to hide inside a cabinet now have to disappear into the wall. Every layout choice in a remodel is a decision about pipe, which is why the plumbing conversation belongs at the design stage, not after demo day surprises everyone.

Take the two upgrades we rough in most. A curbless shower only works when drainage is engineered into the structure itself: the pan area gets recessed or the subfloor rebuilt so the finished floor can fall toward a drain placed around your tile layout, center point or linear. A wall-hung toilet hangs from a steel carrier concealed inside the framing, plumbed, anchored, and tested long before drywall. The powder room photo here is the finished look. The carrier photo beside it is what makes that look possible.

Both come standard within the complete remodel plumbing scope we carry, from demo-day disconnects to the last fixture. And if a floating toilet is the one upgrade you want without remodeling the whole room, our toilet installation and repair page covers carrier installs as a stand-alone project.

Bathroom Capabilities

The upgrades Portland bathrooms are asking for.

Six requests that show up on nearly every bathroom project we plumb, from the practical to the indulgent. All of them live or die at rough-in.

Tub-to-shower conversions

The tub comes out, the drain moves and resizes for a pan, and the valve lands where the new glass needs it. One project turns a dated alcove into a walk-in shower you use every day.

Curbless and zero-entry showers

Slope built into the structure so the floor itself drains: recessed pans, rebuilt subfloor sections, and center or linear drains positioned for the tile layout. Striking now, practical for aging in place.

Freestanding tub supply and drains

Floor-mounted fillers and through-floor drains only look effortless when the stub-outs hit their exact marks. We set the supports and rough-ins so the tub sits precisely where the drawings promise.

Double vanities

A second sink means added supply lines, a second trap, and venting done properly rather than a quick tee fitting. Both bowls drain quietly and neither one waits on hot water.

Steam-ready and thermostatic valves

Multi-outlet shower systems, thermostatic mixing, and rough-ins prepped for a future steam unit all go in at framing stage. Decide on the experience now and the wall will be ready for it.

Bidet seats and wall-hung toilets

In-wall carriers for floating Toto installs, plus water-side prep for bidet seats. We coordinate the electrical with your other trades so nothing ends up running on an extension cord.

The Jewelry

The fixtures go on last, and they go on straight.

Designers call fixtures the jewelry of the room for a reason: they are the part everyone touches and sees every single day. We install Vola, Brizo, and Toto regularly, along with whatever your designer has specified, and we treat trim day like finish carpentry for plumbing. Escutcheons sit flush against the tile. Handles land level with each other. A shower column centers on its tile line instead of splitting a grout joint by an eighth of an inch.

Multi-outlet systems are where trim quality is actually decided, months earlier, at rough-in. A thermostatic setup feeding a rain head, a hand shower, and body sprays only feels seamless when every valve body was set at the exact depth and height its trim requires. That is why we ask for fixture spec sheets before a single wall opens. Our shower valve page goes deeper on valve types, including what thermostatic control actually buys you at six in the morning.

Already fallen for a specific faucet somewhere else? Bring it. We confirm compatibility between the rough valve and your trim before ordering closes, flag mismatches while they are still cheap to fix, and back every connection with our workmanship warranty in writing.

Working With Your Remodel

Built to fit your remodel schedule, not fight it.

Most bathroom remodels squeeze four or five trades into the smallest room in the house on the tightest calendar of the project. Our job as your plumber is to never be the reason that calendar slips. Bids come back promptly, every visit lands inside an exact 30-minute arrival slot instead of a half-day window, and our rough-ins are staged the way city inspectors expect them, so your tile setter starts on schedule instead of waiting on a correction. It is why GCs and designers bring us in as the plumbing sub on their remodels.

Running the project yourself? You get the same discipline plus a translator. We walk the sequence with you on a free video call so you know exactly when plumbing happens relative to demo, tile, and glass, and which decisions have to be locked by each stage. And when the remodel bug spreads down the hall, our kitchen remodel plumbing page covers islands, pot fillers, and sink moves with the same crew.

Scope before demo

A free consultation and a 5-minute video walkthrough turn your fixture list into an exact, guaranteed price in writing before anything is torn out.

Rough-in and inspection

Drains, vents, and supplies move to the new layout while the room is open, pressure-tested and inspected under the permit we file for you.

The quiet middle

Waterproofing, tile, and glass belong to other trades. We hand off cleanly, stay reachable for questions, and book the return visit to the day.

Trim-out and final

Valves get their trim, fixtures set level and centered, every outlet runs hot and cold, and the worksite is disinfected before we call it done.

Good Questions

Bathroom remodel plumbing, question by question.

Can you move the toilet or the shower drain to a new spot?

Yes, and it is the most common request in bathroom remodel plumbing. How involved it gets depends on what is under the floor: a joist bay running the right direction makes a drain move straightforward, while a concrete slab or an inconveniently placed beam calls for more planning. We scope it on a free 5-minute video call, tell you plainly what your structure allows, and put an exact price in writing before demolition starts.

What does a curbless shower need under the floor?

Room for the floor to fall. A standard shower hides its slope inside a curb, while a curbless one builds that slope into the structure, which usually means recessing the pan area between the joists or building up the surrounding floor. Drain placement matters just as much: a linear drain at the wall lets the whole floor pitch in one direction, which tile setters appreciate. We plan all of it with your tile contractor before rough-in so the waterproofing and the plumbing agree.

What is involved in a tub-to-shower conversion?

More than swapping fixtures, less than gutting the room. The old tub and its drain come out, the drain is relocated and resized for a shower pan, the valve usually moves to a better height, and we coordinate blocking for glass and future grab bars with your contractor. After the rough-in passes inspection, your tile or surround goes up and we return to set the trim. The glass shower in our photos above started exactly this way.

Can you install fixtures we bought ourselves?

Gladly. Send us the spec sheets before rough-in and we will confirm the in-wall valve matches the trim, the tub filler has the support it needs, and the drain lands where that particular tub wants it. The one thing we ask is to check compatibility before your return window closes, because a mismatched valve discovered on trim day is an expensive way to learn a part number. Our workmanship warranty covers our installation either way.

How do you keep dust and mess out of the rest of the house?

With the same concierge protocol we bring to every job. Runners go down from the front door to the bathroom before tools come in, floors and landscaping along the path stay protected, and the workspace is disinfected before we leave. During multi-day phases we stage water shutoffs so the rest of the house keeps running, and our office follows up afterward to confirm the room and everything on the way to it was left clean.
