Is A Bidet Attachment Worth Installing Over Using Toilet Paper

For decades, toilet paper has been the standard for post-toilet hygiene in Western cultures. Yet as awareness grows around personal health, sustainability, and comfort, more people are questioning whether this long-standing norm is truly optimal. Enter the bidet attachment—a simple, affordable device that connects directly to your existing toilet and delivers a stream of water for cleansing. While common in parts of Europe, Asia, and South America, bidets are gaining traction in North America as users discover their benefits. But is making the switch really worth it?

The answer depends on what you value: hygiene, cost-efficiency, environmental responsibility, or comfort. This article breaks down the key considerations, compares bidet use with traditional toilet paper, and provides actionable insights to help you make an informed decision.

Hygiene: Water vs. Wiping

From a medical standpoint, cleaning with water is inherently more effective than dry wiping. Toilet paper may remove surface residue, but it often smears rather than eliminates bacteria, especially in sensitive areas. Moist wipes offer better results but come with their own drawbacks—many contain chemicals, fragrances, and non-biodegradable materials that can irritate skin or clog plumbing.

A bidet attachment uses a targeted stream of water to rinse away waste thoroughly. This reduces the risk of irritation, infection, and lingering odor. For individuals with hemorrhoids, anal fissures, or mobility issues, the gentle spray can be significantly more comfortable than abrasive wiping.

“Water cleansing is superior for perianal hygiene. It reduces microtrauma to delicate tissues and lowers the chance of bacterial transfer.” — Dr. Lena Patel, Gastroenterology Specialist

Tip: After using a bidet, pat dry with a small amount of toilet paper or a reusable towel—this minimizes friction and improves comfort.

Cost Comparison Over Time

At first glance, toilet paper seems inexpensive. A 12-roll pack might cost $5–$8. But usage adds up quickly. The average American uses about 100 rolls per year. At $7 per pack of 12, that’s roughly $60 annually per person. For a family of four, annual spending exceeds $240—before taxes and delivery fees.

In contrast, a basic bidet attachment costs between $30 and $80. Most models require no electricity or complex installation—just a connection to the toilet’s water supply line. Once installed, the only ongoing “cost” is minimal water usage (about one-eighth of a gallon per use) and occasional maintenance.

Even with conservative estimates, a bidet pays for itself within 6 to 12 months. After that, savings accumulate each year. High-end electronic models with heated seats or air dryers take longer to recoup costs, but basic cold-water attachments deliver fast ROI.

Factor	Toilet Paper (Annual)	Bidet Attachment (One-Time + Maintenance)
Initial Cost	$0 (already in use)	$30–$80
Recurring Annual Cost	$60 (per person)	$0–$5 (cleaning, minor parts)
Lifespan	N/A (continuous purchase)	5–10 years
Total 5-Year Cost (Per Person)	$300	$30–$80

Environmental Impact: Waste Reduction That Adds Up

Toilet paper production is resource-intensive. According to the Natural Resources Defense Council (NRDC), the U.S. consumes approximately 36 million tons of toilet paper annually. This requires cutting down nearly 15 million trees and consuming billions of gallons of water and energy in manufacturing and transportation.

Additionally, used toilet paper contributes to sewage load. While flushable, it breaks down slowly and can contribute to blockages, especially when combined with fats or wipes. In regions with aging infrastructure, excessive TP use strains wastewater systems.

Bidet attachments drastically reduce reliance on toilet paper. Most users still use a small amount for drying, but consumption drops by 75% or more. Over time, this translates into fewer trees cut, less packaging waste, and reduced carbon emissions from shipping bulky rolls.

Tip: Pair your bidet with reusable cotton rounds or a dedicated drying towel to eliminate disposable paper entirely.

Installation and Practicality

One common concern is complexity: “Will I need a plumber?” For most bidet attachments, the answer is no. These devices install in under 30 minutes using basic tools. The process typically involves:

1. Turning off the water supply to the toilet.
2. Removing the existing toilet tank bolt.
3. Installing a T-valve that splits water flow to both tank and bidet.
4. Connecting the bidet hose to the valve.
5. Attaching the bidet nozzle to the side of the toilet bowl.
6. Restoring water and testing for leaks.

No drilling, no rewiring, no permanent modifications. If you’re comfortable changing a faucet washer or installing a showerhead, you can handle a bidet attachment.

Space isn’t an issue either—the unit fits discreetly behind the toilet and doesn’t interfere with seating. Controls are usually manual dials for water pressure and spray direction. Some premium models include self-cleaning nozzles and adjustable angles.

Mini Case Study: The Johnson Family’s Switch

The Johnsons, a family of five in Portland, Oregon, installed bidet attachments across three bathrooms in early 2022. Prior to the switch, they were buying bulk toilet paper online—roughly 600 rolls per year at a cost of $350. They also dealt with frequent septic tank backups due to high paper volume.

After installation, they reduced toilet paper use to about 150 rolls annually, primarily for drying. Within eight months, their savings covered the cost of the bidets. Two years later, they report fewer plumbing issues, improved comfort (especially for their elderly grandmother), and pride in reducing their environmental footprint.

“We thought it would feel strange,” says Sarah Johnson. “But after the first week, we couldn’t imagine going back. It’s cleaner, gentler, and honestly, kind of luxurious.”

Common Concerns Addressed

Despite growing popularity, misconceptions persist. Let’s address the most frequent objections:

• “It’s unhygienic.” – The opposite is true. Bidet nozzles are designed with self-cleaning mechanisms and antimicrobial materials. Water rinses away bacteria more effectively than wiping, which can spread contaminants.
• “It uses too much water.” – A typical bidet uses less than 1/8 gallon per use. Compare that to the 37 gallons of water required to produce a single roll of toilet paper.
• “It’s only for people with health issues.” – While bidets benefit those with hemorrhoids, incontinence, or limited mobility, they enhance comfort and cleanliness for everyone.
• “It will damage my toilet.” – No evidence supports this. Bidet attachments connect externally and don’t affect porcelain integrity. Millions are in use worldwide without incident.

Expert Insight: Why Medicine Favors Water Cleansing

Medical professionals have long advocated for water-based cleansing in certain conditions. In Japan and South Korea, where bidet toilets are standard, rates of anal discomfort and irritation are notably lower than in countries reliant on dry wiping.

“In postoperative care, we instruct patients to use sitz baths or handheld showers. If water is healing after surgery, why not use it daily for routine hygiene?” — Dr. Arjun Mehta, Colorectal Surgeon

Studies published in journals like *Clinical Gastroenterology and Hepatology* suggest that consistent mechanical wiping can exacerbate anal fissures and pruritus ani (chronic itching). Water, especially warm water, soothes tissues and promotes healing.
