I’ve written a lot about toilet paper on this blog, comparing brand names and store brands. In order to be as objective as possible with my toilet paper analysis, I’ve tried to use measurable data. While I feel like personal opinion is valuable, I wanted to try to be as scientific as possible with my toilet paper testing. In this post, I will explain the toilet paper experiments that I did to arrive at my “bottom” line (get it? bottom?).
Toilet Paper Tests
The toilet paper tests I performed were:
- Value for the Price
I tried to word all of the tests so that all tests have the same result name:
- High is for the things most people would say are good. Strong, soft, thick, absorbent, comfortable, free of lint, easy to dissolve, and great value for the price
- Low is for the things most people would say are bad. Weak, scratchy, thing, not absorbent, uncomfortable, linty, doesn’t dissolve, low value for the price
Of course, it would be unlikely to get a high rating in all areas, so you have to decide which factors are most important to you.
Toilet Paper Strength Test
To test the toilet paper strength, we taped one sheet of paper onto the bottom of our kitchen cabinets. Then we attached a bucket to the other end. We slowly added weight to the bucket (mostly marbles and batteries) until the paper ripped. Finally, we measured how much weight the paper held before it ripped. We ran the test three times and took an average for each brand.
Strength ratings were divided as follows:
- Low: 20 ounces or less
- Medium: 21-30 ounces
- High: 31 ounces or more
Toilet Paper Softness Test
To determine softness, I had several people touch the toilet papers and rate them for softness. This was surprisingly difficult to do, as everyone defines “soft” a little differently. Does softness mean fluffiness? Slipperiness? Pliability? This was a hard one to rate. Still, when I averaged our rankings, the overall ratings made sense and I grouped them into low, medium, and high softness.
Toilet Paper Thickness Test
In order to be as objective as possible, I attempted to rate the toilet papers for thickness in terms of how opaque they are. If they don’t let light through, then they’re thick, right? I also confirmed my findings by touching them.
To test how transparent or opaque they are, I taped them all to the window to see how much light was let through. I grouped them together into low, medium, and high thickness.
Toilet Paper Absorbency Test
I actually ran two different absorbency tests because I was worried my first wasn’t accurate enough. Surprisingly, the two tests gave similar results to each other. Most brands were pretty similar, so the majority of them got a rating of medium. Two stood out as especially low and one stood out as high.
Test 1 – Water Spread Test
The first test was checking to see how far blue water would spread out when dropped onto a sheet of paper. I then measured how large the circle was after it had spread.
Test 2 – Soak-through Test
For the second test, I wanted to see how many sheets of toilet paper the water would soak through. I dropped blue water onto the roll of toilet paper. Then I unrolled it to see how many sheets had dots of water on them.
For later rounds of toilet paper testing, I decided to only use the soak-through test since it was easier and seemed consistent with the other test.
Toilet Paper Comfort Test
This was my most subjective test. Basically, I just tried them all out! If I liked it, I gave it a high comfort rating. If I thought it was just OK, I gave it a medium rating. If I didn’t like it, I gave it a low comfort rating. This is completely the opinion of a “toilet paper princess”!
Toilet Paper Lint-Free Test
Many people would prefer their toilet paper to be lint-free. This is both for the cleanliness of their private parts, as well as the cleanliness of their bathroom. I had difficulty designing a test for this factor until I realized that facial hair stubble would work perfectly. A certain male test subject (who would prefer to remain anonymous) allowed me to rub toilet paper on his unshaven face to see which ones generated the most lint. Like with absorbency, most of the brands were similar on this test so I gave the majority a medium rating. Only one stood out as truly lint-free so I gave it a high rating. Two brands that produced a large amount of lint got a low lint-free rating.
Toilet Paper Dissolving Test
Anyone who has ever used a plunger knows that how well toilet paper dissolves is important! Those with septic tanks are especially interested in this factor. To test how easily the toilet paper dissolves, I put 2 cups of cold water in my mixer with the dough hook attachment. Then I add 3 sheets of toilet paper, turned it on stir, and started the timer. I recorded how quickly the toilet paper dissolved.
The ratings for dissolving were divided as follows:
- High: Dissolved in less than 20 seconds
- Medium: Dissolved in 21-50 seconds
- Low: Took 51 or more seconds to dissolve
Toilet Paper Value Test
To determine a toilet paper’s value rating, I looked at prices. Part of the reason I wrote the posts about the cheapest Cottonelle toilet paper and cheapest Charmin toilet paper first was that I needed prices to compare. I discovered while writing those posts that toilet paper pricing is ridiculously complicated! Comparing prices between brands gets even more complicated because there are different sheet sizes. The fairest way to compare prices would be to compare price per square foot instead of price per sheet. After analyzing the numbers, though, I found that they ranked the same whether I looked at square footage or sheets, so I am going to concentrate on sheets for simplicity. I ranked them by price per 1,000 sheets like this:
- High: Less than $2.00 per 1,000 sheets
- Medium: Between $2.00-2.50 per 1,000 sheets
- Low: Above $2.50 per 1,000 sheets
Note: These price ranges are originally from January 2017. In my second round of testing in March 2018, I raised the ranges slightly since prices had risen. The High, Medium, Low ratings are still as relevant as ever, though.
I based the price comparison on the lowest non-sale prices I could find for that brand. I also did not consider any coupons or subscription discounts. Those could certainly lower prices, but I wanted to find the best value without any hassle.
