Getting a Denver Home Ready for a Winter Walk-In Tub Installation

Why winter is a little different

The installation itself does not change much with the seasons. The old fixture comes out, plumbing and power are adjusted, the new tub is set and tested. Our step-by-step installation guide covers that process. What changes in a Front Range winter is everything around the bathroom: icy steps the crew has to carry a heavy tub up, a front door that will be open longer than usual, plumbing in exterior walls that is colder than it is in July, and a water heater that has to work harder because the water coming into the house is colder.

None of these are reasons to wait until spring. A safer bathroom matters most in the season when people are already more likely to slip outside and less likely to leave the house. They are reasons to spend an hour preparing.

Before the crew arrives

• Clear and de-ice the whole route, not just the front steps: driveway, walk, steps, porch and the entry rug. Shovel early on the morning of the install and again if it snows. In the City and County of Denver, residents are already expected to clear their sidewalks within 24 hours after a storm ends, so this doubles as getting ahead of the city rule.
• Leave room to park close. Snowbanks narrow streets. Move cars out of the driveway if you can, so the delivery vehicle does not have to park a long, icy walk away.
• Put down a mat or old towels inside the door. Crews will be in and out with snow on their boots. Floor protection along the route is part of a good installer's routine, but an extra absorbent mat at the door saves your floors.
• Plan for the open door. The front door may stand open for stretches while the old tub goes out and the new one comes in. Close doors to rooms you want to keep warm, and move pets and anyone sensitive to cold to a warm room away from the entry.
• Know where the main water shutoff is. Denver Water notes that in most single-family homes it is in the basement or crawl space, on the wall facing the street. Make sure it is reachable, not buried behind holiday storage.

Anyone who lives in the home and is unsteady on their feet should stay off the walkway entirely on install day. The CDC reports that about one in four adults 65 and older falls each year, and an icy walk full of activity is exactly the wrong place to test it.

Pipes and cold exterior walls

Many Denver bathrooms, especially in brick ranches and bungalows, have the tub on an exterior wall. Once the old tub is out, the crew can see the supply lines and the condition of the wall cavity. Winter is a good time to ask about it:

• Insulation behind the tub. If the wall cavity is open, ask whether insulation can be added or replaced before the new surround goes up. It keeps pipes warmer and makes the tub more comfortable to sit against.
• Supply line routing. Ask whether any lines run through an unheated space such as a crawlspace, garage wall or exterior chase. Denver Water recommends insulating pipes on exterior walls and in unheated areas.
• A plan for the next cold snap. Denver Water's cold-weather tips include opening sink and vanity cabinet doors so warm room air reaches the plumbing, keeping an attached garage closed, and letting the faucet farthest from where water enters the house drip slowly during extreme cold. Those habits protect the new tub's plumbing too.

Hot water in January

A walk-in tub holds more water than most standard tubs, and the bather is usually inside while it fills. That makes the water heater more important than people expect, and winter is when it is tested hardest. The water entering your home from the street is noticeably colder in January than in August, so the heater has to add more heat to every gallon, and the same tank delivers less comfortably hot water at the tap.

What to check:

1. Read the label on your water heater. Note the tank size and the first-hour rating. The U.S. Department of Energy explains that first-hour rating, the amount of hot water a tank can deliver in an hour starting full, is the number that matters for peak use.
2. Compare it with the tub's fill volume. Your installer will have the tub's specification. If the numbers are close, a winter bath may end up lukewarm.
3. Space out hot water use. Avoid running the dishwasher, laundry or a shower right before a bath in the cold months.
4. Keep the setting safe. The Consumer Product Safety Commission recommends setting water heaters to 120°F to reduce the risk of scalds. Turning the heater up to compensate for cold weather raises scald risk for older skin. Ask about a properly sized heater or an anti-scald mixing valve instead.

Our features guide explains heated seats and inline heaters, which keep the water warm once it is in the tub but do not replace an adequate water heater.

Keeping the bather warm

The one real drawback of a walk-in tub is that the bather sits in the tub while it fills and while it drains. In a cold bathroom in February, that can be uncomfortable, and being chilled is more than a comfort issue for older adults. The National Institute on Aging warns that older people can lose body heat faster and that a home kept at 60 to 65 degrees may not be warm enough for them.

• Warm the bathroom before the bath. Close the door and let the room heat up from the home's system first.
• Keep a large towel or robe within reach of the seat, and drape it over the shoulders and lap while filling and draining.
• Ask about a fast-drain option and a heated backrest or seat when choosing a model.
• If you use a portable heater, follow the National Fire Protection Association's guidance: keep anything that can burn at least three feet away, plug it directly into a wall outlet, and turn it off when you leave the room. Never place a heater where it could be splashed or knocked into water.
• Have the bather step out onto a non-slip mat, then sit down on a chair or bench to dry off. Warm, relaxed muscles and a cold floor are a common combination before a slip.

If a storm hits on install day

Front Range storms can arrive overnight and leave as fast as they came. If roads are unsafe or your walk cannot be cleared, the right answer is to reschedule. A heavy tub and a slick set of steps are not worth the risk for the crew or for you. When you book, ask how the installer handles weather days and how quickly a postponed job is usually rebooked. If the install will take your only full bathroom out of service, make backup bathing arrangements for that evening in case the job runs long.

The first winter with the new tub

Follow the installer's instructions on when the tub can first be used, since some sealants need time to cure, and cold rooms can slow curing. Over the first few weeks, notice whether the water is staying warm enough, whether the bather is cold while filling, and whether the controls are easy to reach with cold, stiff hands. Small adjustments, such as a robe hook within reach, a towel warmer or a change to the bath routine, make the difference between a tub that gets used and one that does not.
