Cardinal Shower Enclosures Warranty

Important Warnings!

Shower Doors are Not Watertight

Cardinal Shower Enclosures, when properly installed, are designed to prevent leaks under normal shower conditions. Excessive water pressure or directing the shower spray directly at the door do not represent normal shower conditions and can result in leaks.

The amount of water that can escape your shower is also varies depending on the type of shower. A heavy glass swing door shower enclosure with no polycarbonate seals will allow more water to escape under normal conditions than a fully framed swing door shower enclosure. 

For example, if you have two children in the bathtub, and they insist on throwing buckets of water at each other, or shoot each other with squirt guns, or play with the shower nozzle, water will likely get out. Also, you should not clean your shower enclosure with your spray nozzle, which also counts as excessive water pressure. If you notice puddles of water outside your shower after such activities, you should probably clean it up as soon as possible and not repeat whatever activity got the water out of the tub or shower. Continual splashing of water outside your shower can cause all sorts of trouble.

Although some movies & comics show a shower or tub enclosure filled nearly to the top with water (6 feet deep perhaps), these are comic situations and we recommend that you don't try this with a Cardinal Shower Enclosure.

The type of shower enclosure can play a huge difference in the amount of water that may escape your shower. It is perfectly normal for a few bits of water to escape through the small open gaps on a typical heavy glass swing door shower enclosure. Some people like to add a polycarbonate strike jamb or perhaps a bulb seal along the wall jamb side of the door, where others prefer the unobstructed look of pure glass. Those most concerned about water escaping will sometimes select a different type of shower that naturally retains more of the water drops within the unit.

With cast glass, the spacing between a door and panel needs to be slightly wider to accommodate the natural variations in cast glass. A good analogy comes from the world of cars. Having a cast glass enclosure is like getting to drive a fine Italian sports car. It may not be quite as practical day to day, but it is exceedingly beautiful. The customer needs to determine where they fall on the scale from pure beauty to pure functionality.

Towel Bar and Handle Warning

Towel bars and handles are not to be used as grab bars.


For many people, grab bars in showers are a great assistance for getting in and out of the tub or shower. However, if your Cardinal tub or shower enclosure is equipped with a towel bar, you should not use it as a grab bar. It will not support your weight. Do not hang from it. Do not stand on it. If you use excessive force, it could snap off, shatter your shower door, send glass everywhere, or do goodness knows what. If you have small children who love to hang on things, and you are often heard to call them "my little monkeys" (in an affectionate way, of course), it's probably a good idea to instruct them not to hang from the towel bar. However, your towels and washcloths should be quite happy hanging from the towel bars.

Better yet, just use a knob for the inside panel, or upgrade to recessed finger pulls or the Skyline style pulls. They're pretty cool.

Abrasive Cleaner Warning

Do not use abrasive or acid-based cleaners when cleaning your Cardinal Shower Enclosure.

There are some powerful cleaners on the market today. Abrasive or acid-based cleaners can scar the metal or glass of your Cardinal Shower Enclosure. It probably wouldn't happen with a single application, but it's best to use appropriate types of cleaners all the time.

Maintaining Your Glass

For best results, Cardinal Shower Enclosures should be cleaned with a squeegee or towel after exposure to water.

Cardinal 10 Care and Maintenance

After each use a simple swipe of a squeegee will help maintain that brand new look. The glass needs to be cleaned every few weeks using a damp microfiber cloth and a mild detergent or soap to remove soap scum and grime from the glass. If you prefer, a general glass cleaner and a cloth are also suitable.The need to use harsh cleansers or toxic chemicals is no longer necessary to maintain the pristine appearance of your glass. When cleaning your treated glass be careful not to use any rough, gritty, highly acidic or abrasive cleaners that may remove the surface of the glass and damage the coating, therefore voiding the warranty. For areas with hard water, due to a higher concentrate of mineral deposits such as lime and calcium, a build up may occur on the protective coating and not be easily removed with a mild detergent. A solution of white vinegar and water (1 part vinegar to 5 parts water), will need to be used occasionally to dissolve these deposits.


The manufacturer has tested and approved the following products as preferred cleaners for Cardinal 10 Surface Protection:

  • Windex
  • Lysol 4in1 Bathroom Cleaner
  • Fantastic Orange Action
  • Green Works Natural Glass & Surface Cleaner
  • Clean Shower Daily Shower Cleaner
  • Mixture of 1 part vinegar to 5 parts water

Some individuals wait a long time to clean their enclosures (weeks, months, etc.), and then express concern that they can't get water spots, mold, or other things off of their shower enclosures. It all depends on how clean you want your enclosure. For the best results, Cardinal Shower Enclosures should be cleaned with a squeegee or towel after exposure to water, or in the case of Cardinal 10, by following the instructions above.

Warning about Opening & Closing Your Shower Door

Do not use excessive force when opening & closing your Cardinal Shower Enclosure.

All of us at some point get angry. Some people are physically strong, some are naturally aggressive. If you use excessive force when opening or closing your Cardinal Shower Enclosure, you could shatter the glass. I mean, it is glass for goodness sake.

Shower Enclosure Structural Warning

Do not hang from or stand on your Cardinal Shower Enclosure.

It's not designed to support your weight, so just don't do it.

A Warning About Thunder

A shattering experience about a shower enclosure.

This story was forwarded to us by Art of Dedand, FL:

"I installed a two panel sliding clear shower door enclosure with hardware over my fiberglass tub in December of 2004. The shower is rarely used since it is in our second bathroom. In August of 2006 I went into the bathroom the day after a violent lightning / thunderstorm, and found my shower door had exploded into millions of small ¼” pieces. I immediately looked for damage to the walls and windows around the tub for evidence of a lightning strike, but found none. The other door and door hardware were fine. My only conclusion is that the sound vibration from the lightning strike shook the door and it either shattered by itself or was shaken into the shower door aluminum frame and shattered on impact."

His enclosure was not a Cardinal Shower enclosure. This is probably a one in a million occurrence, and unfortunately it happened to Art, but that's why shower door manufacturers use tempered glass. In the event that the glass does break, you'll have millions of tiny pieces instead of sharp edged blades of glass.

Glass Obscurity Warning

Make sure to consider all the important factors when selecting the obscurity level of your glass.

It's expensive to change your glass after your shower enclosure is installed, so we recommend that you consider all the factors that could be important to you. Do you own a mountain cabin, and have a lovely view through the enclosure out the window? In that case you might consider clear or Starfire glass to be your best option. Do you prefer a certain degree of privacy when showering? Perhaps an obscure pattern would be right for you. Is your shower enclosure the showpiece of your master bathroom? You might consider using Cardinal Art Glass. And, of course, we all remember the gorilla story.

Warning to People who Fish

If you are cleaning fish in the shower, we recommend that you thoroughly remove all fish innards and sanitize your enclosure soon as your are finished.

Not doing so can cause all sorts of trouble, especially if your have a significant other who is about to shower and doesn't appreciate the fine aroma of freshly caught & cleaned fish.
