It's the only color changing shower curtain I've seen yet, and I couldn't wait to test it out, just in time for Halloween. Overall, great quality and the color changes just as advertised. Love how the "blood" actually DRIPS and runs down the curtain when wet. It surprises me a little everytime I shower/ splash water on it, and definitely makes showering a bit more entertaining! Great concept! Now I can't wait to show my friends and family this when they come over!

Changes quickly and is such a realistic red! I scared my boyfriend quite nicely! Thank you! The surface does feel papery, so it’s not one you should use regularly, but it’s good for a nice prank!

Exactly as described, it is amazing and horrifying and wonderful in the guest bathroom (where no warning is given).

This was ordered as a Christmas gift but we had to try it! The mat was packaged perfectly, arrived quickly and worked great! Highly recommend this!

My son loves this thing!

Pretty cool shower curtain, kids love it. It’s a little stiff and heavy, but that actually serves as a benefit by keeping the water inside the shower. I also put one in our guest bathroom and our adult guest thought it was cool too.

The colour change on this is AWESOME! I love leaving dripping hand prints when I shower in the morning - it starts my days off right. My only complaint, and this doesn't change the fact that I love it, is that even after using it daily for a couple weeks, it is rather stiff, but that is due to the thickness and newness of the material. It is well worth buying, especially if you don't tell houseguests that the colour will change.

Lovely product! Got it for my new place and excited to use it to drive my friends insane!

It is great, just the effect I was looking for.

I really had my doubts about this product after ordering other cheap Halloween themed products over the years. BUT, I was pleasantly surprised! The product worked BETTER than I expected. I used it as a shower liner. It's true that one side looks slightly pink, which I assumed was the color changing side. However I was wrong. The color changing side is truly white. Once I hung it up correctly, I took my first shower with the product. It was so much fun. I couldn't believe that the product actually changed as soon as the water hit it, and it was as advertised BLOOD RED! The next morning I was surprised that the product turned completely white once it was dry, and the product worked again. Just as advertised! And the product didn't run, so no red or pink stains.

Pretty Bloody if you ask me...

Lots of fun. Color changing is great, only downfall is it is a paper type material. Water resistant but doesn't slide open and closed well, like cloth or plastic.

Just got it yesterday. Hung it up and the kids loved it. Really cool effect. Color change is instant when it gets wet. You can even make splatter patterns. Happy with purchase.
★ ★ ★ ★
The product itself is great, you just have to make sure you know the facts about the product first. The product is single sided, which is in the description, but the color changing side is on the inside of the shower which is hard to tell based off the images. The materal itself is strong and would be hard to rip even on purpose and is very good at catching the shower water. I had to cut my curtain down to fit in my shower which seemed to cause some slight discoloration at the bottom, but that is very minor and it did not have this effect on the side.

Frequently Asked Questions

Does this mat actually change color when wet?

Yes! The brand-new Bloody Bath Mat is the first bath mat of its kind and actually changes color when wet with water

How do I unroll the sheet?

Your mat comes rolled for safe shipping and easy storage. Unroll and flatten with a heavy rug before first use.

How thin is the sheet?

Each white mat sheet is invisibly thin, about the width of a thick sheet of construction paper. Made from a non-slip plastic, the color effect feels like walking on a painted sheet. We recommend to buy more than one for the ultimate scare and cover your entire bathroom floor!

How should I care for my mat?

Wipe and hang to air dry after each use. The color will not drip off. Caution: If you don't hang up to dry, color stains most likely will appear when the water has dried. Please read the Important Safety Instructions before use.
